3. Intended use
The laboratory power unit serves as a potential-free DC voltage source to operate low-voltage consumers. The adjustable output can be tapped with up to 5 A at the front and up to the full nominal current at the back. The front output is limited to 5 A and protected against overload. When switching the outputs of several power supplies in series, voltages of >75V / DC , which are dangerous to touch, may be generated. This is why insulated lines/measuring cables must be used for safety reasons for voltages above this. Connection on the front is performed with 4 mm safety sockets, on the back with high-current socket screw connectors. The outputs (front and back) are connected to each other.
The connection cables used must be large enough. Where the conductor section is too small, overheating and fire may result.
The output data of the laboratory measuring devices is as follows:
| Type Output voltage Output current | |
| HPS-11530 1 - 15 V/DC 0 - 30 A | |
| HPS-11560 1 - 15 V/DC 0 - 60 A | |
| HPS-13015 1 - 30 V/DC 0 - 15 A | |
| HPS-13030 1 - 30 V/DC 0 - 30 A | |
| HPS-16010 1 - 60 V/DC 0 - 10 A |
Current and voltage can be set continually through digital rotary controls using coarse and fine settings in order to allow fast and precise value settings. The values are displayed on the structured LC display. A power limit for constant power operation can be pre-set without a shorting bar.
The power unit can be remote-controlled An external voltage (0 - 5 V/DC) or external potentiometer (5 kOhm) can be used to set the output voltage and output current. The DC output is turned on and off via the a switching contact.
Model HPS-11560 also has a remote sensor function (SENSE). The voltage drop in case of high load currents can be compensated for this way. The output voltage at the consumer remains absolutely stable and independent from the load.
Three freely programmable memory slots can be assigned to different fixed voltages and current limitations. The selection switch is located at the back of the device.
The device is overload- and short-circuit-proof and contains a safety temperature cut-off.
The laboratory power unit is designed in compliance with protection class 1. It is only approved for connection to shockproof sockets with protective grounding and an alternating current of 230V / AC commonly used in households.
The mains socket must be located close to the device and easily accessible, or an emergency stop fixture must be available.

8. Operation
The laboratory power unit is not a charger. To charge batteries, use suitable chargers with a charging current cut-off.
During a longer period of operation under nominal load, the surface of the housing will heat up. Attention! Risk of burns! Therefore, make sure that there is adequate ventilation of the power unit and never operate it partly or fully covered to avoid any damage.
When connecting a consumer, ensure that it is not connected when switched on. A switched-on consumer can result in sparks when connecting to the output terminals of the power unit, which in turn can damage the sockets or the connected cables and/or their clamps.
If your power unit is not required, switch it off and disconnect it from the mains. The displays remain on for a few seconds after it is switched off to unload the internal capacitors and to store the last parameters that were set.
Always ensure a sufficient conductor cross-section for the DC connection lines, since overload may cause fire in the line.
a) Connecting the power cable
- Connect the supplied grounding mains cable to the low-power device installation socket (18) on the power unit. Ensure a tight fit.
- Connect the power cable to a shockproof mains socket with protective grounding. The maximum length of the power cable to the outlet must not exceed 3m
b) Unit Installation
Place the laboratory power unit on a stable, level and robust surface. Make sure that ventilation slots in the casing are not covered up.
c) General Informations
The laboratory power unit is micro-processor-controlled and is operated through two digital controls (incremental encoders without end position) with sensor function. This enables fine and coarse control via a control.
After the device switches on, a system check is performed. The test status is displayed on the two displays.
The displays are in the following order:
Display of the current software state.
Segment test to determine if the display works with all its individual segments.
Then the LED displays "C.V.", "C.C." and "REAR CONTROL" are tested.
System test of the protective devices starts.
The over-voltage protection is tested.
The over-load protection is tested.
The over-temperature protection is tested.
Fan test The fan is shortly tested throughout the speed range. For a short time, the fan speed increases audibly
The remote control function for "output out" is tested. After this step, the device switches to the regular operating display mode.
The power unit enables operation in 4 modes. These modes are selected by the "MODE" (13) slider on the back. The following modes are possible:
Normal Normal operation. Voltage and current are adjusted on the front.
Preset
Memory slot operation Three fixed voltages can be stored in the device and directly selected through this "Preset" function. The memory slot is selected with the "RECALL" (15) slider. The front controls are inactive.
Remote Ctrl
Remote control operation. The power unit can be remote-controlled via an external voltage or external poti. The remote settings can be performed for voltage and current. The front controls are inactive.
Set
Settings operation. The three preset slots can be programmed freely. Select the memory slot with the "RECALL" (15) slider and make the settings using the controls (7, 8).
The separate operating modes are described in more detail in the following.
d) Added functions
The power supply is auto-zeroed every time you turn it on. In case you need to zero the unit during operation and do not want to restart it, zero it manually.
- Press and hold the VOLTAGE control knob for approx. 30 s to enter the MENU mode. "CCO" and "no" are displayed.
- Rotate the CURRENT control knob until "CCO" and "YES" are displayed.
- Press the CURRENT control knob once to zero the unit. "YES" lights up in the display to confirm successful zeroing.
- Press the VOLTAGE control knob to exit the MENU mode.
e) Normal operation
In normal operation, the power unit can be operated through the front controls.
- Ensure that the "MODE" slider is in the "Normal" position.
- Remove any connected consumers from output (9 and 10 or 11 and 12).
- Switch on the power unit at the power switch (1). The display (2 and 3) lights up, and after a short selftest, the current and voltage displays appear.
→
Set the current limitation before setting any voltages. If the current value is too high, your connection lines can be damaged; if it is too low (<1 A), the output voltage can be limited.
MODE
Set current limitation
Limiting the output current is a protection mechanism to protect the consumer or connection cables. Current limitation can be pre-set at the output without any short circuit. The power unit then supplies the maximum current set.
- Remove any connected consumers from the power unit.
- Switch on the power unit at the power switch (1). The display (2 and 3) lights up, and after a short selftest, the current and voltage displays appear.
- Set the current limitation at the "CURRENT" control according to your application.
- Turn the control and a current limitation value appears.
Where no setting is made within 3 seconds, the display switches back to the current display.
- Turn the control to the left or right to set the current limitation. After switching on, the fine settings area (0.1 A) is always active. This is indicated by a slightly lighter digit.
Press the rotary control slightly from the front. The decimal position (1.0 or 0.1) of the setting range changes each time you press. Turning changes the value.
Settings can be made coarsely (whole numbers) or fine (by tenths).
Where the desired current value was set, the display switches back to normal display after 3 seconds.
If the preset current is reached in normal operation, the power unit switches to current limitation mode and reduces the voltage value. This operation is signalled with the red status display "C.C." (5).
Set output voltage
The output voltage can be set at the "VOLTAGE" (7) control. The coarse and fine control is performed in the same way as for setting the current limitation.
With the large control range, it is possible that the voltage setting takes approx. 1-2 seconds to switch from a high to a low voltage value.
In normal mode the device operates in constant voltage mode. This means that the power unit emits a constant, preset output voltage. This operation is indicated with a green status display "CV" (4).
Connecting a load
When connecting a consumer, make sure that it is connected to the power unit when switched off. The maximum current consumption of the device to be connected must not exceed the capacity indicated in the technical specifications.
For serial connection of the outputs with several power supplies, the resulting voltages can be fatal on contact (>70V / DC) . As of this voltage, you may only use insulated accessories.
Avoid the use of non-insulated metallic cables and contacts.
All these exposed areas must be covered with suitable, flame-resistant insulation materials or by other measures and be protected from direct contact and short circuits.
Ensure a sufficient cable diameter for the intended current.
The power unit has two outputs. These outputs always have the same output voltage. The difference, however, is in the current carrying capacity.
At the front sockets (9 and 10), only a current of max. 5 A can be tapped. An automated current limitation is integrated.
The screw sockets on the back are indicated for full nominal current.
From an output current of 20 A, the screw clamp function of the rear sockets is recommended to avoid overheating of the plug sockets.
- Remove any connected consumers from the output.
- Switch on the power unit at the power switch (1). The operating display (2/3) lights up and the current and voltage display appears on the display.
- Set the parameters according to your specifications as described in the chapter "Start-Up".
- Check once more that the correct output voltage is set.
- Connect the plus pole (+) of the consumer with the red socket "+" and the minus pole (-) of the consumer with the blue socket "-" of the respective output (front = "AUX. OUTPUT", rear = "MAIN OUTPUT").
- Now you can switch on the connected consumer.
The current consumption of the connected consumer is displayed in Ampere (A) in the display (3).
f) Memory slot operation “Preset” and “Set”
Three fixed voltages, including current settings, can be stored in the device with the "Set" function and directly selected through the "Preset" function.
Ex works, all three memory slots (P1, P2, P3) are preset.
They are assigned as follows:
| Memory Type | P1 P1 P1 | |||||
| Voltage Current Voltage Current Voltage Current | ||||||
| HPS-11530 | 5 V Maximum 13.8 V Maximum | 15 V | Maximum | |||
| HPS-11560 15 V | ||||||
| HPS-13015 25 V | ||||||
| HPS-13030 25 V | ||||||
| HPS-16015 55 V | ||||||
Make sure that no consumers are connected.
- Activate the "Preset" function through the "MODE" (13) slider on the rear. Put the switch in the "Preset" position. The front LED display "REAR CONTROL" (6) lights up. The front rotary controls are now inactive.
- Select the respective memory slot "P1, P2 or P3" on the rear slider. The respective output voltage is indicated on the display (2).
- Now you can connect and switch on the consumer.
For deactivating the fixed voltage function, slide the "MODE" (13) slider back to the "Normal" position. The LED display "REAR CONTROL" (6) goes out. The device switches back to normal power unit operation (always remove DC consumers before!)
Assigning memory slots with "Set"
All three memory slots can be assigned user-specific values for output voltage and current limitation.
Make sure that no consumers are connected.
For this purpose, proceed as follows:
- Activate the "Set" function through the "MODE" (13) slider on the rear. Put the switch in the "Set" position. The front LED display "REAR CONTROL" (6) lights up.
- Select the respective memory slot "P1, P2 or P3" on the rear "RECALL" (15) slider. The respective values for current and voltage are indicated on the display (2/3). The front rotary controls (7 and 8) can be used to set the desired output voltage and current limitation.
If required, repeat these steps with the other memory slots.
- When all parameters are set, slide the "MODE" (13) slider back to the "Preset" position for fixed voltage operation or to the "Normal" position for standard operation.
g) Resetting output presets (P1/P2/P3) to factory default values
The power supply allows for presetting three voltage values (including current settings) by means of three memory slots: P1, P2, and P3. In case you want to reset the memory slots to the factory default values during operation, do the following.
- Press and hold the VOLTAGE control knob for approx. 30 s to enter the MENU mode. "CCO" and "no" are displayed.
- Rotate the VOLTAGE control knob until "rPr" and "no" are displayed.
- Rotate the CURRENT control knob until "rPr" and "YES" are displayed.
- Press the CURRENT control knob once to reset the preset values. "YES" lights up when the values have been successfully reset.
- Press the VOLTAGE control knob to exit the MENU mode.
h) Remote control operation "Remote Ctrl"
Through the built-in "Remote control" connection (16), the voltage and current can be set through an external voltage source or an external adjustable resistance (short "poti"). The remote control is connected on the rear "Remote Control" built-in plug (16). There is a remote socket included for connection.
In remote-controlled operation, the current control path must also be connected, since the output otherwise switches to the current limitation mode "C.C." and limits the output voltage.
Preparation of the remote control connection
- Turn the lateral screw of the supplied socket and remove the front, black contact socket turning it slightly.
- Draw five connecting cables with a conductor cross-section of at least 0.34mm^2 through the metal sleeve from the rear. Carefully solder these cables to the soldering lugs no. 1, 2, 3, 4 and 5 of the black contact socket. Ensure that no short circuits are created.
The numbers of the soldering lugs are indicated on the black insulator.

9. “SENSE” FUNCTION (HPS-11560 ONLY)
The HPS-11560 has an automatic voltage control for the rear high-current output. For this, two separate measuring cables are connected parallel to the connecting cables. The potential drop which occurs on the connecting cables is measured on these two measuring cables. The laboratory power unit automatically compensates for this voltage drop so that the actually set voltage is supplied to the consumer.
Proceed as follows for connection:
Always connect the supply cables from the power unit to the consumer first. Pay attention to correct polarity.
Press the clamp release on the rear SENSE connection inwards with a small screwdriver and insert the cables into the terminal openings. Check that they are plugged firmly.
Now connect the two "SENSE" cables to the consumer observing the correct polarity. The conductor cross-section for the "SENSE" cables must be at least 0.34mm^2
Always slacken the connection in the reverse order (first of all "SENSE" cables and then the connecting cables).
Make sure that you contact the SENSE cables as close as possible to the connecting point of the consumer. Observe correct polarity.
Never short-circuit the "SENSE" cables.
10. Protective device
The power unit has several integrated automatic protective devices that protect the power unit from damage. The activated protective devices are displayed with letter codes and the DC output is switched off for safety reasons at the same time.
When a protective devices is active, the consumer must be switched off and disconnected from the power unit immediately.
To reactivate the output, switch off the power unit. Wait until all displays have gone out. Switch on the power unit again. The power unit should work normally again. Where this is not the case, please contact our customer service.
The following displays are possible:
Over-voltage protection
A higher external voltage than provided by the power unit was determined at the DC output. The output is switched off.
The current levels for switching off are listed in the technical data.
Over-heating protection
The integrated temperature sensor determined that the system temperature is too high.
To prevent overheating, the output is switched off.
Turn off the power unit and let it cool down for at least 30 minutes.
After switching it on, check if the fan or ventilation apertures are blocked. During the startup self-test stage, the fan must start up audibly. Where this is not the case, please contact our customer service.
Overload protection
In case of overload at the DC output, the power limitation is usually switched on. If this is not the case, the second protective function becomes active.
Switch off the power unit at once when this warning message appears and check the connection data of the consumer. Remove the consumer from the power unit's DC output.
Switch on the power unit again and check its function. If the error message remains on, please contact our customer service.
