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 .

V CV R_L=R_C VSET R_L>R_C Crossover point CC R_L

Slew Rate

Theory

The PPX has selectable slew rates for CC and CV mode. This gives the PPX power supply the ability to limit the current/voltage draw of the power supply. Slew rate settings are divided into High Speed Priority and Slew Rate Priority. High speed priority mode will use the fastest slew rate for the instrument. Slew Rate Priority mode allows for user adjustable slew rates for CC or CV mode. The rising and falling slew rate can be set independently. 

High Speed Priority mode Slew rate = Enabled

Bleeder Control

Background The PPX DC power supplies employ a bleed resistor in parallel with the output terminals. 

PPX Bleed resistor Load

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. $$ \mathrm{R} _ {\mathrm{D}} (\Omega) \leq \mathrm{E} _ {\mathrm{O}} (\mathrm{V}) \div \mathrm{I} _ {\mathrm{R}} (\mathrm{A}) $$ 

PPX RD Eo Load IR Output Current + - IR

 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. Reverse Current: Accumulative energy. When the power supply is connected to a load such as a battery, reverse current may flow back to the power supply. To prevent damage to the power supply, use a reverse-current-protection diode in series between the power supply and load. 

PPX Diode Load

CAUTION

Ensure the reverse withstand voltage of the diode is able to withstand 2 times the rated output voltage of the power supply and the forward current capacity can withstand 3 to 10 times the rated output current of the power supply. Ensure the diode is able to withstand the heat generated in the following scenarios. When the diode is used to limit reverse voltage, remote sensing cannot be used.

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.

WARNING

Dangerous voltages. Ensure that the power to the instrument is disabled before handling the power supply output terminals. Failing to do so may lead to electric shock.

Connection with the front panel output terminal

Menu Tree

Convention

Use the menu trees as a handy reference for the power supply functions and properties. The PPX-1005/PPX-2002/PPX-2005/PPX-3601/PPX-3603/PPX-10H01 menu system is arranged in a hierarchical tree. Each hierarchical level, which is coated in varied colors, can be navigated through the orders within the diagrams below. For example: To set the measurement average high: ① Press the Menu key. ② Navigate to the Measurement option. ③ Enter the Measure Average option. ④ Select High.

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.  

Protect Voltage Limit Off UVL 0.000 V OVP Level 22.00 V Current Limit Off OCP Level 2.200 A OCP Delay 0.050 s

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

Setting the Protection Level 3. Scroll the knob key to move among UVL/OVP/OCP Level fields. Click the knob key to enter each field, respectively. Scroll the knob key to adjust value, along with the arrow keys to change among digits followed by clicking the knob key to confirm set value.

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.

Load Sequence Script

Overview

A sequence script can be loaded from either USB disk or internal memory. When USB disk is connected with PPX series, the script file in USB disk has higher priority over internal memory; that is, user can only load script file in USB disk when USB disk is plugged in. Prior to loading script from USB disk, ensure the script file is placed in root directory.

Load script from USB disk

1. Insert a USB disk into the front panel USB-A port. Ensure the USB disk contains a test script in root directory.  2. The icon of USB disk detection will be displayed on the upper status bar after a few seconds if the USB disk is recognized.

^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. 

PPXEXT-\ Analog connector Output Terminal 2 core shielded wire or twisted pair

$$ \mathrm{Pin} 3 \rightarrow \mathrm{EXT-V} (+) $$ $$ \mathrm{Pin4} \rightarrow \mathrm{EXT-V(-)} $$ 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.

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

Note

Maximum output impedance is 10KΩ. Ensure the sensing circuit has an input impedance greater than 1MΩ. The monitor outputs are strictly DC and should not be used to monitor analog components such as transient voltage response or ripple etc.

CAUTION

Ensure IMON (pin 1) and VMON (pin 2) are not shorted together. This may cause damage to the unit. External Operation and Status Monitoring

Background	The analog connector can also be used to monitor the status operation and alarm status of the instrument.
	The pins are isolated from the power supply internal circuitry by photo couplers. Status Com (Pin 20) is a photo coupler emitter output, whilst pins 15~19 are photo coupler collector outputs.
	A maximum of 30V and 8mA can be applied to each pin.
Pinout	Name and Pin	Description
	OUT ON Status	15 On when the output is on (open-collector photocoupler output).1
	CV Status	16 This line is On when the PPX is in CV mode (open-collector photocoupler output).1
	PWR OFF Status	17 Outputs a low level signal when power is turned off. (open-collector photocoupler output).1
	CC Status	18 This line is On when the PPX is in CC mode (open-collector photocoupler output).1
	Alarm Status	19 On when a protection function (OVP, OCP, OTP or AC Alarm) has been activated or when an output shutdown signal is being applied (open-collector photocoupler output).1
	Status COM 20 This is the common line for the status signal pins 15 to 19.

F_AQ

• 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^ C±5°C. 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].
