2. 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 >75 V/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.

Operation under adverse environmental conditions is not permitted. Unfavourable ambient conditions are:

- moisture or high humidity

- dust and combustible gases, vapours or solvents

- thunderstorms or similar conditions such as strong electrostatic fields etc.

Any use other than that described above damages the product. Moreover, this is linked to dangers such as short circuits, fire, electric shock, etc. No part of the product may be modified or rebuilt!

7. FUNCTIONAL DESCRIPTION

• The laboratory power unit works with highly developed combinational circuit technology and active PFC (power factor correction). This ensures a stable output voltage and a high degree of effectiveness. The DC outputs are isolated and feature a protective isolation against the mains voltage. For the secondary DC connection, there are two coloured safety sockets on the front (max. 5A) and two high-load terminal screw clamps on the back (full nominal current range).
• The structured display shows the voltage and current (V = Volt = unit of electric voltage, A = Ampere = unit of electric current) and the status display in case of device interferences.
• Various protective mechanisms, e.g. overload protection, current limitation, overheating protection, etc. are built in for secure and reliable operation.
• The power unit is cooled through a temperature-controlled fan. Therefore, ensure sufficient air circulation.
• The output voltage and output current at the power unit are infinitely adjustable.

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 3 m.

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:

-EU 3.0

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).

MODE

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.

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 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 (> 70 VDC). 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:

Type\Memory	P1 P2 P3
	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.

MODE Normal Preset Remote Ctrl Set P1 P2 RECALL P3

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.

MODE

RECALL

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.

Check the switching function for correct function.

When the DC output is switched off, "O P OFF" is displayed.

If this remote control function is no longer required, put the MODE switch to the "Normal" position.

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 0.34mm2.

Always slacken the connection in the reverse order (first of all "SENSE" cables and then the connecting cables).

HPS-11560 OUTPUT SENSE INPUT

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 DEVICES

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 start-up 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.

11. DISPOSAL

Electronic devices are recyclable waste and must not be disposed of in the household waste.

end of its service life, dispose of the product according to the relevant statutory regulations.

You thus fulfil your statutory obligations and contribute to the protection of the environment.

12. MAINTENANCE AND CLEANING

Apart from an occasional cleaning or exchanging the fuse, this laboratory power unit is maintenancefree. Use a clean, lint-free, antistatic and dry cloth to clean the device. Do not use any abrasive or chemical agents or detergents containing solvents.

Exchanging the Fuse

If it is no longer possible to switch on the laboratory power unit, the rear mains fuse (19) is probably defective.

Proceed as follows to replace the mains fuse:

Switch off the power unit and remove all the connection cables and the mains plug from the device.

Lever the rear fuse holder (19) with a suitable screwdriver from the bracket.

Replace the defective fuse with a new fine-wire fuse (5 x 20 mm) of the same type and rated current. The fuse value is listed in the chapter on "Technical Data".

Press the fuse insert into the fuse holder.

13. TROUBLESHOOTING

By purchasing the laboratory power unit, you have acquired a product that is reliable and operationally safe.

Nevertheless, problems or errors may occur.

For this reason we want to describe how to troubleshoot potential malfunctions:

Always follow the safety instructions!

Error Possible cause
The power unit cannot be switched on.	Does the operating display light up on the power unit (2)?Check the mains voltage (you may also want to check the mains fuse in the device or the line circuit breaker).
Connected consumer devices do not work.	Is the voltage set correctly?Is the polarity correct?Check the technical data of the consumers.
The “REAR CONTROL” display is lit. The device can not be operated via the rotary controls.	Remote control operation is active.Put the rear “MODE” slider into the “Normal” position.
The “O P PFF” display is lit. The DC output was switched off through the remote control output (16).Release the connection between contacts 4 and 5.The output is switched on again.
The output current is limited to 5 A, although the current settings are higher.	The front connection is limited to no more than 5 A.For higher currents, connect the consumer to the rear main output.
The “CC” LED is lit. Constant current operationThe preset current was exceeded. Check power consumption on your con-sumer and increase the current limitation on your power unit, if applicable.
The “C.V.” display is lit. Constant current operationThe power unit works normally.The output provides the constant voltage set.
