7. COMMISSIONING AND OPERATION
a) Connection and operation
• Place the lab mains unit on a firm and level surface.
• First switch off the lab mains unit (put the on/off switch (15) in the "O" position).
• If a consumer is connected to the DC output sockets (6, 12), disconnect it.
• Connect the mains socket (13) to a mains outlet with a protective ground via the included mains cable.
• First switch on the lab mains unit (put the on/off switch (15) in the "I" position).
• The display now shows the currently set output voltage and the value for current limitation.
At the DC output sockets (6, 12), the output voltage will only be available when you briefly push the button
"OUTPUT ON" so that the button lights up red.
b) Selection of the voltage/current range
The lab mains unit has three voltage/current ranges that you can choose via three buttons:
"16V/5A" button (5)
The lab mains unit delivers an output voltage of 0 - 16 V/DC and a current of 0 - 5 A (max.).
"27V/3A" button (11)
The lab mains unit delivers an output voltage of 0 - 27 V/DC and a current of 0 - 3 A (max.).
"36V/2.2A" button (10)
The lab mains unit delivers an output voltage of 0 - 36 V/DC and a current of 0 - 2.2 A (max.).
After pushing the respective button, it lights up. The display shows the currently set output voltage and the
value for current limitation.
The last value set remains saved after the lab mains unit is switched off.
The setting of the respective output voltage and the current limitation is described in the next section.
Observe:
If the DC output is activated (red LED in the button "OUTPUT ON" (4) is lit) and you push one of the three
buttons, the DC output is deactivated for reasons of safety (red LED goes out).
