Remote control operation “remote”
The laboratory power unit can be remote controlled via external direct current. The control voltage is 0 -
2.3 V/DC and controls the entire adjustment range of the corresponding output proportionally. Remote
control operation is only possible in individual and serial mode.
The current setting controls of both outputs may not be located in the minimum
position (left stop), otherwise it is not possible to use the entire setting range for
the voltage. For remote control operation, the voltage controls must be set to
maximum to provide the full adjustment range.
Disconnect consumers connected to outputs A and B and turn the power unit off.
On the back of the device, remove the plastic cover of the respective terminal strip. Terminal strip (28) for
output A, terminal strip (29) for output B.
Remove the shorting bar between the clamps “V ref OUT“ and “V ref IN“
Connect the positive terminal of the external control voltage to the clamps “V ref IN“ and the negative ter-
minal to the clamp “COMMON“ an.
Reattach the plastic cover to the terminal strip.
Switch on the power unit at the power switch (1). The operating display (2) lights up and the current and
voltage display appears on the display.
Operate the selection switch for individual or serial mode. The red indicator above the switch is lit.
Set the current limit according to your specifications as described in the chapter “Commissioning”. Now
the voltage is only set via the external control voltage.
Verify again that the output voltage has been set correctly.
Connect the positive terminal (+) of the consumer with the red socket “+” and the negative terminal (-) of
the consumer with the blue socket “-” of the respective output.
Now you can switch on the connected consumer.
For normal control through the controls on the device, you have to replace the
shorting bar at the back between the “V ref OUT” and “V ref IN” clamps.
