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 re may result. The output data of the laboratory measuring devices is as follows: Type Output voltage Output current (Total, MAIN + AUX)
Current and voltage can be set continually through digital rotary controls using coarse and ne 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. Three freely programmable memory slots can be assigned to different xed voltages and current limitations. The selection switch is located at the back of the device. With the software included and the USB connection, the power supply can be controlled by a personal computer for running cyclical operations. Up to 20 programmable sets of voltage and current at different time durations can be programmed into the operation and the cyclical operations can be repeated up to 999 times.37 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 230 V/AC commonly used in households. Unauthorised conversion and/or modication of the device are inadmissible because of safety and approval reasons (CE).

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 sufcient conductor cross-section for the DC connection lines, since overload may cause re in the line. Connecting the Power Cable
1. Connect the supplied grounding mains cable to the low-power device installation socket (12) on
the power unit. Ensure a tight t.
2. 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 2 m. 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. 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 ne 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.42 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 measures 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” (8) 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 xed voltages can be stored in the device and directly selected through this “Preset” function. The memory slot is selected with the “RECALL” (9) slider. The front controls are inactive.43 Remote Ctrl Remote control operation. The power unit can be remote-controlled via an external voltage or external potentiometer. 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” (9) slider and make the settings using the controls (3, 4). The separate operating modes are described in more detail in the following. 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.
1. Press and hold the VOLTAGE control knob for approx. 30 s to enter the MENU mode. “CCO” and
2. Rotate the CURRENT control knob until “CCO” and “YES” are displayed.

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 (6 or 7). Switch on the power unit at the power switch (5). The display (1) lights up, and after a short self test, 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.
1. Remove any connected consumers from the power unit.
2. Switch on the power unit at the power switch (5). The display (1) lights up, and after a short self
test, the current and voltage displays appear.
3. Set the current limitation at the “CURRENT” control (4) according to your application.
4. 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.
5. Turn the control to the left or right to set the current limitation. After switching on, the ne 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.
6. Settings can be made coarsely (whole numbers) or ne (by tenths).
7. 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.“ (1).45 Set output voltage The output voltage can be set at the “VOLTAGE” (3) control. The coarse and ne 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 LED “C.V.“ (1). 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 specications. For serial connection of the outputs with several power supplies, the resulting voltages can be fatal on contact (> 75 V/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, ame-resistant insulation materials or by other measures and be protected from direct contact and short circuits. Ensure a sufcient 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 (6), 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.46

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 (1) on the power unit light up?
- Check the mains voltage (you may also want to check the mains fuse in the device or the line circuit breaker).60 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 (10). 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 output current is limited to 5 A. For higher currents, connect the consumer to the rear main output. The “C.C.” LED is lit. Constant current operation: The preset current was exceeded. Check power consumption on your consumer and increase the current limitation on your power unit, if applicable. The “C.V.” LED is lit. Constant voltage operation: The power unit works normally. The output provides the constant voltage set. OVP Over-voltage protection: See chapter PROTECTIVE MEASURES. OtP Overheating protection: See chapter PROTECTIVE MEASURES. OLP Overload-protection: See chapter PROTECTIVE MEASURES. Repairs other than those described above may only be carried out by an authorised specialist.
