8. NormAL oPErATIoN

The power supply can be operated via the front setting controller in normal operation. Remove the connected
consumer from the output (6).
Switch on the power supply via the PowEr (1) on/off switch.
The display (2) lights up and the voltage and current display appears after a short self-test.
First set the current limit before each voltage setting. Your connecting cables can be damaged by a high
current value. The output voltage can be limited by a low current value (<1A).

a) Set current limit

A protective mechanism limits the output current to protect the consumer or the connecting cables. The current
limitation can be preset without short circuiting at the output. The power supply then delivers the maximum preset
current.
1. Remove the connected consumer from the power supply.
2. Switch on the power supply PowEr on/off switch (1). The display (2) lights up and after a short self test the
voltage and current display appears.
3. Set the current limiter on the CurrENT setting controller (5) according to your needs.
4. Turn the controller and the current limitation value appears.
The display switches back to the current power display if a setting is not made within 2 seconds.
5. Turn the setting controller to the left or right to set the current limitation. This is represented by a slightly lighter
digit. Briefly press the setting controller. The decimal point (1.0 or 0.1) of the setting range changes each time
the button is pressed. Turning changes the value.
6. The setting can be made roughly (in the unit range) or precisely (in the one tenth range).
7. The display automatically switches back to normal display after approximately 2 seconds if the desired current
value was set.
The power supply switches to current limitation mode and also reduces the voltage value if the preset current
strength is reached in normal operation. This operation is signaled with the red C.C. status display (2).

b) Set output voltage

The output voltage can be set at the VoLTAgE (4) setting control. The rough and fine control is carried out in the
same way as the setting of the current limitation.
It could be that the voltage setting requires approx. 1-2 seconds to adjust from a high to a low
voltage value through the large control range.
The device works in constant voltage mode during normal operation. This means that the power supply
delivers a constant preset output voltage. This mode is signaled with the green C.V. status display (2).
