Frequently Asked Questions - PPX-3601 GW Instek

How often should the PPX-3601 be calibrated?

The PPX-3601 should be calibrated by an authorized service center at least every 2 years. For calibration details, contact your local dealer or GW Instek.

Why is the OVP voltage triggered earlier than expected?

The OVP level is measured at the output terminals, not at the load. Voltage drop across load cables can cause the OVP to trip earlier. Ensure cable resistance is minimized and consider using remote sensing for accurate protection.

Can I combine multiple cables for output wiring?

Yes, cables can be paralleled if a single cable's current capacity is insufficient. Twist cables together, ensure equal length, and verify the withstand voltage rating meets requirements.

The accuracy does not match the specification. What should I check?

Allow the unit to warm up for at least 30 minutes at 23°C ±5°C. Check that test leads are properly connected and use 4-wire sensing for best accuracy. If issues persist, contact support.

How do I reset the PPX-3601 to factory defaults?

Press Menu, navigate to Save/Recall, select Recall Mem Set, choose 'Default', and confirm. This restores all settings to factory defaults (see manual Appendix for default values).

What is the bleeder resistor and when should it be turned off?

The bleeder resistor discharges filter capacitors when the output is off. For battery charging, turn it off to prevent battery discharge. It can be toggled in Menu > Utility > Bleeder.

How do I use remote sensing on the PPX-3601?

Connect +S to load positive and -S to load negative. Set Remote Sense to 4-Wire in Menu > Output. Ensure sense cables have voltage rating exceeding isolation voltage. Do not connect with output on.

What interfaces are available for remote control?

Built-in USB (CDC), RS-232/485, and LAN (TCP/IP sockets, web server). Optional GPIB can be factory-installed. Refer to the Communication Interface chapter for configuration.

Can I log measurement data?

Yes, use the Data Logger feature (D-Log button). Set sample period (0.1-999.9 s), choose Save USB (CSV to USB drive) or Send Remote (real-time via interface). Up to 1000 files per subfolder.

How do I set up a sequence test?

Press Test to enter Sequence mode. Create a CSV script with steps: time, voltage, current, etc. Load via USB or internal memory (t001-t010). Configure cycle, number of runs, and trigger options. Press Run to start.

Theory of Operation

The theory of operation chapter describes the basic principles of operation, protection modes and important considerations that must be taken into account before use.

Operating Description

Background

The PPX power supplies are regulated DC power supplies with a stable voltage and current output. These operate within a switch automatically between constant voltage and constant current according to changes in the load.

Suitable supply cord set for use with the equipment:

• Mains plug: shall be national approval
• Mains connector: C13 type

• Cable:

• Length of power supply cord: less than 3m

• Cross-section of conductors: at least 0.75mm^2
• Cord type: shall meet the requirements of IEC 60227 or IEC 60245 (e.g.: H05VV-F, H05RN-F)

Caution

If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.

CC and CV Mode

CC and CV mode Description

When the power supply is operating in constant current mode (CC) a constant current will be supplied to the load. When in constant current mode the voltage output can vary, whilst the current remains constant. When the load resistance increases to the point where the set current limit ( I_SET ) can no longer be sustained the power supply switches to CV mode. The point where the power supply switches modes is the crossover point.

When the power supply is operating in CV mode, a constant voltage will be supplied to the load, whilst the current will vary as the load varies. At the point that the load resistance is too low to maintain a constant voltage, the power supply will switch to CC mode and maintain the set current limit.

The conditions that determine whether the power supply operates in CC or CV ( V_SET ), the load resistance ( R_L ) and the critical resistance ( R_C ). The critical resistance is determined by V_SET/I_SET . The power supply will operate in CV mode when the load resistance is greater than the critical resistance. This means that the voltage output will be equal to the V_SET voltage but the current will be less than I_SET . If the load resistance is reduced to the point that the current output reaches the I_SET level, the power supply switches to CC mode.

Conversely the power supply will operate in CC mode when the load resistance is less than the critical resistance. In CC mode the current output is equal to I_SET and the voltage output is less than V_SET .

Bleeder Control

Background The PPX DC power supplies employ a bleed resistor in parallel with the output terminals.  Bleed resistors are designed to dissipate the power from the power supply filter capacitors when power is turned off and the load is disconnected. Without a bleed resistor, power may remain charged on the filter capacitors for some time and be potentially hazardous. In addition, bleed resistors also allow for smoother voltage regulation of the power supply as the bleed resistor acts as a minimum voltage load. The bleed resistance can be turned on or off using the configuration settings.  Note By default the bleed resistance is on. For battery charging applications, be sure to turn the bleed resistance off as the bleed resistor can discharge the connected battery when the unit is off.

Alarms

The PPX power supplies have a number of protection features. When one of the protection alarms is set, the ALM icon on the display will be lit. For details on how to set the protection modes, please see page 47.

OVP

Over voltage protection (OVP) prevents a high voltage from damaging the load. This alarm can be set by the user.

OCP

Over current protection prevents high current from damaging the load. This alarm can be set by the user.

UVL

Under voltage limit. This function sets a minimum voltage setting level for the output. It can be set by the user.

OTP

Over temperature protection protect the instrument from overheating

AC ALARM

When AC input voltage or frequency is abnormal or beyond the AC power range under operation, the alarm will be generated.

SENSE ALARM

This alarm function is activated when real output voltage is larger than sense output voltage.

Alarm output

Alarms are output via the analog control connector. The alarm output is an isolated open-collector photo coupler output.

Considerations

The following situations should be taken into consideration when using the power supply.

Inrush current	When the power supply switch is first turned on, an inrush current is generated. Ensure there is enough power available for the power supply when first turned on, especially if a number of units are turned on at the same time.
Caution	Cycling the power on and off quickly can cause the inrush current limiting circuit to fail as well as reduce the working life of the input fuse and power switch.
Pulsed or Peaked loads	When the load has current peaks or is pulsed, it is possible for the maximum current to exceed the mean current value. The PPX power supply ammeter only indicates mean current values, which means for pulsed current loads, the actual current can exceed the indicated value. For pulsed loads, the current limit must be increased, or a power supply with a greater capacity must be chosen. As shown below, a pulsed load may exceed the current limit and the indicated current on the power supply ammeter.

Current limit level Measured Ammeter current 

Pure electrical circuit lines without any symbols

Reverse Current: Regenerative load When the power supply is connected to a regenerative load such as a transformer or inverter, reverse current will feed back to the power supply. The PPX power supply cannot absorb reverse current. For loads that create reverse current, connect a resistor in parallel (dummy load) to the power supply to bypass the reverse current. To calculate the resistance for the dummy resistor, R_D , first determine the maximum reverse current, I_R , and determine what the output voltage, E_O , will be. $$ \mathrm{R} _ {\mathrm{D}} (\Omega) \leq \mathrm{E} _ {\mathrm{O}} (\mathrm{V}) \div \mathrm{I} _ {\mathrm{R}} (\mathrm{A}) $$   Note The current output will decrease by the amount of current absorbed by the resistor. Ensure the resistor used can withstand the power capacity of the power supply/load. 

Grounding

The output terminals of the PPX power supplies are isolated with respect to the protective grounding terminal. The insulation capacity of the load, the load cables and other connected devices must be taken into consideration when connected to the protective ground or when floating.

Floating

As the output terminals are floating, the load and all load cables must have an insulation capacity that is greater than the isolation voltage of the power supply.

WARNING

If the insulation capacity of the load and load cables are not greater than the isolation voltage of the power supply, electric shock may occur. Grounded output terminal If the positive or negative terminal is connected to the protective ground terminal, the insulation capacity needed for the load and load cables is greatly reduced. The insulation capacity only needs to be greater than the maximum output voltage of the power supply with respect to ground.

Background	Before connecting the output terminals to a load, the wire gauge of the cables should be considered. It is essential that the current capacity of the load cables is adequate. The rating of the cables must equal or exceed the maximum current rated output of the instrument.
Recommended wire gauge	Wire Gauge	Nominal Cross Section	Maximum Current
	28	0.10	3
	26	0.15	4
	24	0.25	5
	22	0.35	7
	20	0.55	9
	18	1	12
	The maximum temperature rise can only be 60 degrees above the ambient temperature. The ambient temperature must be less than 30 degrees.

Output Terminals

Background

Before connecting the output terminals to the load, first consider whether voltage sense will be used, the gauge of the cable wiring and the withstand voltage of the cables and load.

Basic Operation

This section describes the basic operations required to operate the power supply. Setting OVP/OCP/UVL → from page 47 C.V. priority mode → from page 51 C.C. priority mode from page 55 Display mode → page 59 Panel lock → page 60 Save setups → from page 61 Recall setups → from page 62 Remote sensing → from page 64 Temperature from page 66 Data Logger → from page 71 Before operating the power supply, please see the Getting Started chapter, page 8.

Setting OVP/OCP/UVL Levels

Background

The OVP level and OCP level has a selectable range that is based on the output voltage and output current, respectively. The OVP and OCP level is set to the highest level by default. The actual selectable OVP and OCP range depends on the PPX model. When one of the protection measures are on, the type of alarm message will be shown on display. Press Shift + PROT key to clear any protection alarm messages that have been tripped. By default, the output will turn off when the OVP or OCP protection levels are tripped. The UVL will prevent you from setting a voltage that is less than the UVL setting. The UVL setting range is from 0% \~ 105% of the rated output voltage. Before setting the protection settings: \- Ensure the load is not connected. \- Ensure the output is turned off.

Note

You can enter the PROT setting to apply limits to the voltage and current settings, respectively. You can set limitations so that the values do not exceed the set OVP and the set OCP level, and so that the values are not lower than the set UVL trip point. By using this feature, you can avoid turning the output off by mistakenly setting the voltage or current to a value that exceeds the set OVP or OCP level or to a value that is lower than the set UVL trip point. If you have selected to limit the voltage setting, you will no longer be able to set the output voltage to a value that is above about 95% of the OVP trip point or to a value that is lower than the UVL trip point. If you have selected to limit the current setting, you will no longer be able to set the output current to a value that is above about 95% of the OCP trip point. Lastly, the Delay time setting for OCP delays trigger for OCP by set time period.

Steps

1. Press the PROT key to enter the Protect page.   Enable/Disable Voltage and Current Limit 2. Scroll the knob key to move between Voltage/Current Limit fields. Click the knob key to enter each field, respectively. Scroll the knob key to turn ON/OFF the function. Further click the knob key again to confirm your setting. Option On, Off

PPX-10H01	0.05~1.1	5~110	0~105


Note

- The UVL setting range is from 0% \~ 105% of the rated output voltage. It depends on Voltage Limit On/Off to activate/deactivate UVL setting. - The OVP setting range is from 5% \~ 110% of the rated output voltage. - The OCP setting range is from 5% \~ 110% of the rated output current.

Remote Sensing

Remote sense is used to compensate for the voltage drop seen across load cables due to the resistance inherent in the load cables. The remote sense terminals are connected to the load terminals to determine the voltage drop across the load cables. Remote sense can compensate up to 1 volt for PPX-1005/2002/2005/3601/3603 and 3 volts for PPX-10H01 (compensation voltage). Load cables should be chosen with a voltage drop less than the compensation voltage. 

WARNING

Ensure the output is off before handling the remote sense connector. Use sense cables with a voltage rating exceeding the isolation voltage of the power supply. Never connect sensing cables when the output is on. Electric shock or damage to the power supply could result. Output terminal Connector Overview When using the remote sensing, make sure the wires that are used follow the following guidelines: Wire gauge: AWG 20 to AWG 14 Strip length: 6.5mm // 0.26 in.  -S +S +S: +Sense terminal -S: -Sense terminal 

Note

Be sure to remove the Sense joining cables so the units are not using local sensing.

Single Load

1. Connect the +S terminal to the positive potential of the load. Connect the -S terminal to the negative potential of the load.

2. Operate the instrument as normal. See the Basic Operation chapter for details. Wire Shielding and Load line impedance To help to minimize the oscillation due to the inductance and capacitance of the load cables, use an electrolytic capacitor in parallel with the load terminals. To minimize the effect of load line impedance use twisted wire pairing. Shield the sense wires and connect the shield to the chassis ground. 

Temperature

The PPX series can measure DUT temperature while power output simultaneously. Prior to temperature measurement, utilize the optional accessory GTL-205A, which includes a temperature probe adaptor with thermocouple K type, to connect between DUT and TC input on the front panel of PPX series. The optional GTL-205A Temperature probe adaptor with thermocouple K type with 1000mm in length.

^1 Open collector output: Maximum voltage of 30 V and maximum current of 8 mA. The common line for the status pins is floating (isolated voltage of 60 V or less). It is isolated from the output and control circuits.

External Voltage Control of Voltage Output

Background

External voltage control of the voltage output is accomplished using the analog control connector on the rear panel. A voltage of 0\~10V is used to control the full scale voltage of the instrument, where: Output voltage = full scale voltage × (external voltage/10)

Connection

When connecting the external voltage source to the analog connector, use shielded or twisted paired wiring.  $$ \mathrm{Pin} 3 \rightarrow \mathrm{EXT-V} (+) $$ $$ \mathrm{Pin4} \rightarrow \mathrm{EXT-V(-)} $$ Wire shield → negative (-) output terminal

Connection-alt. shielding

If the wire shield needs to be grounded at the voltage source (EXT-V), then the shield cannot also be grounded at the negative (-) terminal output of the PPX power supply. This would short the output.  $$ \mathrm{Pin3} \rightarrow \mathrm{EXT-V(+)} $$ $$ \mathrm{Pin4} \rightarrow \mathrm{EXT-V(-)} $$ Wire shield → EXT-V ground (GND)

Panel operation

1. Connect the external voltage according to the connection diagrams above. 2. Set the CV Control as External V. Page 108 Also, set Output Type per application and turn On Output Enable. 3. Press the Output key. The voltage can now be controlled with the External voltage.   The input impedance for external voltage control is a high impedance OPA input.  Use a stable voltage supply for the external voltage control.  CV and CC Slew Rate Priority (CVLS, CCLS) are disabled when using external voltage control. See the CVLS and CCLS Settings on page 51 & 55.  Ensure no more than 10.5 volts are input into the external voltage input. Ensure the voltage polarity is correct when connecting the external voltage.

External Voltage Control of Current Output

Background

External voltage control of the current output is accomplished using the analog control connector on the rear panel. A voltage of 0\~10V is used to control the full scale current of the instrument, where: Output current = full scale current × (external voltage/10)

Connection

When connecting the external voltage source to the analog connector, use shielded or twisted paired wiring.  Connection-alt. shielding If the wire shield needs to be grounded at the voltage source (EXT-V), then the shield cannot also be grounded at the negative (-) terminal output of the PPX power supply. This would short the output.  Steps 1. Connect the external voltage according to the connection diagrams above. 2. Set the CC Control as External V. Page 108 Also, set Output Type per application and turn On Output Enable. 3. Press the Output key. The current can now be controlled with the External voltage.   The input impedance for external voltage control is a high impedance OPA input.  Use a stable voltage supply for the external voltage control.  CV and CC Slew Rate Priority (CVLS, CCLS) are disabled when using external voltage control. See the CVLS and CCLS Settings on page 51 & 55.  Ensure no more than 10.5 volts are input into the external voltage input. Ensure the voltage polarity is correct when connecting the external voltage.

External Resistance Control of Voltage Output

Background

External resistance control of the voltage output is accomplished using the analog connector on the rear panel. A resistance of 0 10k is used to control the full scale voltage of the instrument. The output voltage (0 to full scale) can be controlled with the external resistance from 0 10k . Output voltage = full scale voltage x (external resistance/10)

Connection

 Pin3 → EXT-R Pin4 → EXT-R Wire shield → negative (-) output terminal

Steps

1. Connect the external resistance according to the connection diagrams above. 2. Set the CV Control as External R. Page 108 Also, set Output Type per application and turn On Output Enable.

	3. Press the Output key. The voltage can now be controlled with the External resistance.
!Note	Ensure the resistor(s) and cables used exceed the isolation voltage of the power supply. For example: insulation tubes with a withstand voltage higher than the power supply can be used.When choosing an external resistor ensure the resistor can withstand a high degree of heat.
!Note	CV and CC Slew Rate Priority (CVLS, CCLS) are disabled when using external resistance control.See the CVLS and CCLS Settings on page 51 & 55.

External Resistance Control of Current Output

Background

External resistance control of the current output is accomplished using the analog connector on the rear panel. A resistance of 0Ω~10kΩ is used to control the full scale current of the instrument.The output current (0 to full scale) can be controlled with the external resistance from 0Ω~10kΩ.Output current = full scale current × (external resistance/10)

Connection

 Pin5 → EXT-R Pin6 → EXT-R Wire shield → negative (-) output terminal

CV and CC Slew Rate Priority (CVLS, CCLS) are disabled when using external resistance control. See the CVLS and CCLS Settings on page 51 & 55.

External Control of Output

Background

The output can be turned on or off externally using a switch. The analog control connector can be set to turn the output on from a high or low signal. The voltage across pins 9 and 12 are internally pulled to +5V with 2kΩ pull-up resistor. A short (closed switch) produces a low signal. When set to High = On, the output is turned on when the pins 9 and 12 are open. When Low = On, the output is turned on when the pins 9 and 12 are shorted.

Connection


Steps

1. Connect the external switch according to the connection diagrams above. 2. Set Output Type per application to High or Low and turn On Output Enable. Page 108 3. The switch is now ready to set the output on or off.  When using a switch over long distances, please use a switch relay to extend the line from the coil side of the relay.

If a single switch control is to be used for multiple units, please isolate each instrument. This can be achieved by using a relay.  Ensure the cables used and the switch exceed the isolation voltage of the power supply. For example: insulation tubes with a withstand voltage higher than the power supply can be used.  Output ON/OFF Delay Time (Output On/Off Dly) are disabled when the output is set to external control. See the Output Delay settings on page 108.

External Trigger In / Out

Background

Pin 10 is used for the external trigger input and pin 11 is used as the trigger output. Pin 12 is the B common for both pins. The trigger input can be configured to perform an action such as toggling the output on/off, load a memory setting or apply a voltage/current setting when a trigger is received. The trigger output can be configured to be active when the output is turned on/off, a voltage/current setting is changed or when a memory setting has been recalled. The trigger output pulse width can also be configured. See page 120 for details on the trigger input and trigger output configuration settings.

Remote Monitoring

The PPX power supplies have remote monitoring support for current and voltage output. They also support monitoring of operation and alarm status. External monitoring of output voltage and current → from page 173 External monitoring of operation mode and alarm status → from page 175

External Voltage and Current Monitoring

Background

The analog connector is used to monitor the current (IMON) or voltage (VMON) output. An output of 0\~10V represents the voltage or current output of 0\~ rated current/voltage output. $$ \mathrm{IMON} = (\text { current output / full scale }) \times 1 0. $$ $$ \mathrm{VMON} = (\text { voltage output / full scale }) \times 1 0. $$ External voltage and current monitoring doesn't need to be enabled in the configuration settings.

VMON Connection

 $$ \mathrm{Pin4} \rightarrow \mathrm{Neg} (-) $$ $$ \mathrm{Pin2} \rightarrow \mathrm{Pos(+)} $$

Configure Ethernet Connection

The Ethernet interface can be configured for a number of different applications. Ethernet can be configured for basic remote control or monitoring using a web server or it can be configured as a socket server. The PPX series supports both DHCP connections so the instrument can be automatically connected to an existing network or alternatively, network settings can be manually configured.

Ethernet configuration	For details on how to configure the Ethernet settings, please see the configuration chapter on page 138.

FAQ

• How often should the power supply be calibrated? • The OVP voltage is triggered earlier than expected. • Can I combine more than 1 cable together for the output wiring? • The accuracy does not match the specification. How often should the power supply be calibrated? The PPX should be calibrated by an authorized service center at least every 2 years. For details regarding calibration, see your local dealer or GWInstek at www.gwinstek.com / [e-mail]. The OVP voltage is triggered earlier than expected. When setting the OVP voltage, take into account the voltage drop from the load cables. As the OVP level is set from the output terminals and not the load terminals, the voltage at the load terminals may be slightly lower. Can I combine more than 1 cable together for the output wiring? Yes. Cables can be used together (in parallel) if the current capacity of a single cable is insufficient. However the withstand voltage should also be taken into account. Ensure the cables are twisted together and are the same length. The accuracy does not match the specification. Make sure the device is powered On for at least 30 minutes, within 23^ ± 5^ . This is necessary to stabilize the unit to match the specification. For more information, contact your local dealer or GWInstek at www.gwinstek.com / [e-mail].
