UVL voltage limitation
The UVL function allows you to set the top voltage limit. If this voltage limit is exceeded, the DC output
cuts off automatically and signals this with the indicator light „ALM" (12). Reduce the output voltage. To
activate the DC output, press the button „OUTPUT ON" (5). The warning indicator „ALM" goes off.
To program, proceed as follows:
- Turn the laboratory power unit on and wait approx. 1-2 seconds.
- Press the button „UVL/Voltage" (2). The status display „UVL" (9) is lit.
- The display „V" (8) shows the current voltage limit.
- Carefully insert a small screwdriver (blade width max. 3 mm) into the
opening „Upper Voltage Limit" (15). Carefully set the desired voltage
limit via the internal precision regulator.
- You leave the setup range by again pressing the button „UVL" (5).
The indicator (9) will go off. The set value is preserved even when
turning the device off.
Setting the voltage and the current
The laboratory power unit also allows you to set the voltage and current limit when the output is switched
off. The advantage is that you do not have to simulate a short circuit at the output to adjust the current
limit. Setting the output current is a protection mechanism to protect the consumer or connection cables.
To program, proceed as follows:
- Turn the laboratory power unit on and wait approx. 1-2 seconds.
- Select the desired output range via the buttons „RANGE" (4). The
corresponding LED lights up. For safety reasons, the active DC out-
put is deactivated at each range switch.
- Press and hold the button „REVIEW" (3) for the duration of the setup
operation.
- The display shows the voltage and current setting for the activated
DC output.
- Select the voltage via the adjuster „VOLT" (13).
- The current limitation is realised via the adjuster „CURR" (14).
- Let go of the button „REVIEW" (3). The display then shows „0000"
again.
- Direct voltage setting is possible with an active output.
