Front panel 

1. Mains switch

2. Switch output on/off (standby)

Position 

on 

= output voltage on

Position 

off 

= output voltage off

3.

 

Reset switch

Serves to reset the OVP.

4. Switch Preset/Normal OVP

In position "Preset"  the desired OVP threshold can be set 

by means of a screw driver with the trimmer  OVP  (No. 5) 

Switch back to normal operation after setting it!

5. Trimmer for setting OVP threshold

This trimmer sets the OVP threshold voltage.

6. Local

This switch is used to switch from IEEE bus mode back to 

standard mode.

7. Switch Preset/Actual Voltage

In position Preset the voltmeter 13 indicates the preset 

voltage, adjusted with potentiometer 9. In position Actual 

the actual voltage is indicated.

8. Switch Preset/Actual current

In position Preset the amperemeter 14 indicates the preset  

max. output current, adjusted with potentiometer 12. In 

position Actual the actual current is displayed.

9. Potentiometer Voltage 

Potentiometer for the output voltage adjustment.

10. Potentiometer Current

Potentiometer for the max. output current.

11. Voltmeter

The  voltmeter  displays  the  preset,  actual  and  the  OVP 

voltages. 

12. Ammeter

The ammeter displays the preset and the actual value of 

the output current.
