c) Setting the Current Limitation at the Outputs
First set the permissible operating voltage for the consumer to be operated using the voltage control (3). The lab
mains adapter output must be operated on voltage-controlled condition for this (see Setting the Voltages at the
Outputs).
• Now turn the rotary control for output current limitation (4) counter-clockwise to the left stop. The red LED (8)
for current limitation („CC“) lights up and the green LED (6) for voltage control „CV“ goes out.
• Short-circuit the output sockets of the direct current output (5) with a suitable cable (connect plus and minus of
the same output).
• Now turn the rotary control for output current limitation (4) slowly clockwise from the left stop to the right until
the desired maximum current is flowing. The further the control is turned to the right, the higher the current
value.
• The current applied to the corresponding output is indicated in the corresponding display „A“ (1). Please
observe the maximum current load capacity of the respective output.
• When the desired maximum current is set, switch off the lab mains adapter by pressing the on/off switch (16).
• Remove the short-circuit cable that connected the plus and minus poles of the output.
• Switch on the lab mains adapter again by pressing the on/off switch (16). The current limitation is now adjusted
and the maximum current flow set can no longer be exceeded in current operation.
Please observe that the current limitation for the „3 - 6 V“ voltage outputs cannot be set. If a maximum
current value of 2 A is exceeded for these outputs, a firmly set current limitation triggers automatically.
For monitoring purposes, the LED display (11) for active current limitation „OL“ lights up then. Pressing the
button „SHOW VALUE“ (12) makes it possible to read the current current and voltage values in the respective
display.
Attention!
Operate the „3 - 6 V“ voltage output in overload operation only briefly to avoid excessive heating of the
lab mains adapter.
