Serial operation with master control
Just like normal serial mode, this mode serves to double the voltage of outputs A and B. The difference to
normal serial mode is the control. Voltage and current are controlled exclusively by the adjustment con-
trols of output A. Outputs A and B are switched in series internally. Additional external switching is not
required.
Disconnect consumers connected to outputs A and B.
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.
Press the selection switch “series tracking” (5). The red indicator above the switch is lit.
Set the parameters according to your specifications as described in the chapter “Commissioning”. The volt-
age and current settings are made only through the control of output A. The sum of both
voltage indicators (A and B) equals the output voltage.
Verify again that the output voltage has been set correctly.
Connect the positive terminal (+) of the consumer with the red socket “+” (24) of output A and the nega-
tive terminal (-) with the blue socket “-” (16) of output B.
Now you can switch on the connected consumer.
The current consumption of the connected consumer is indicated on both displays simultaneously. The
current of one display corresponds to the output current.

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.
