The power unit enables operation in 4 modes. These modes are selected by the selection switch
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 selection switch RECALL (9). The front controls are inactive.
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 selection switch RECALL (9) and make the settings using
the control knobs (3, 4).
The separate operating modes are described in more detail in the following.
8. NORMAL OPERATION
In normal operation, the power unit can be operated through the front
controls. Ensure that the selection switch MODE is in the Normal position.
Remove any connected consumers from output (6 or 7).
Switch on the power unit at the On/Off switch POWER (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.
a) 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 On/Off switch POWER (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 control knob CURRENT (4) according to your application.
4. Turn the control and a current limitation value appears.
