Function Elements:
1.
LCD- display of the effective output voltage.
2.
LCD- display of the effective output current.
3.
SPANNUNG: Adjustment of the output voltage.
4.
C.V.: Green LED shows constant voltage.
5.
C.C: Red LED shows constant current LED.
6.
STROM: Adjustment of the output current.
7. +/-: Terminal with safety nuts. Positive and negative
outlet.
8. I/O: On-/Off-switch.
Operation:
Connect the device with an electric outlet.
Turn STROM [6] and SPANNUNG [3] counter clockwise to the stop.
Switch on the device with I/O [8].
Adjust the desired output voltage and the desired output current with the help of SPANNUNG [3] and
STROM [6]. Each effective value is shown on the displays [2 & 1].
Connect the desired consumer load to the terminals + and –.
Adjustment of a Constant Voltage (C.V.):
Turn STROM [6] clockwise up to the stop.
Turn SPANNUNG [3] counter clockwise to the stop.
Switch the device on with I/O [8].
Now the green LED C.V. [4] should show.
Now adjust the desired output voltage with SPANNUNG [3] and the help of the display [1].
Connect the load to the terminals [7] of this device.
Adjustment of a Constant Current (C.C.):
Turn STROM [6] counter clockwise up to the stop.
Turn SPANNUNG [3] counter clockwise to the stop.
Switch the device on with I/O [8].
Short circuit the output terminals by connecting [7].
Turn SPANNUNG [3] clockwise until the red LED C.C. [5] shows.
Turn STROM [6] clockwise until the display [2] shows the desired maximum output current.
Removing the wire from the terminal to end the short circuit.
Connect the load to the terminals [7] of this device.
Do not change the value of the output current as long as the load is connected.
