Functional Description
The laboratory power unit works with highly developed combinational circuit technology and active PFC
(power factor correction). This ensures a stable output voltage and a high degree of effectiveness. The DC
outputs are electrically isolated and feature a protective isolation towards the mains voltage. The secondary
DC connection is effected via two coloured safety sockets.
The concise dual displays show the voltage and current separately for outputs A and B (V = Volt = unit of
electric voltage, A = Ampere = unit of electric current). Output C is displayed via a button on the display of
output B. Via light displays the current condition of the power unit is indicated. Various protective mecha-
nisms, e.g. overload protection, current limitation, overheating protection, etc. are built in for secure and reli-
able operation.
The cooling of the power unit is provided via integrated ventilators. Therefore, ensure sufficient air circu-
lation.
The power unit can set the output voltage and the output current continuously (with output C the voltage
only).
Commissioning
The laboratory power unit is not a charger. To charge batteries, use suitable
chargers with a charging current cut-off.
During a longer period of operation under nominal load, the surface of the hous-
ing will heat up. Attention! Risk of burns! Therefore, make sure that there is ade-
quate ventilation of the power unit and never operate it partly or fully covered to
avoid damage.
When connecting a consumer ensure that it is not connected when switched on.
A switched on consumer can result in sparks when connecting to the output ter-
minals of the power unit, which in turn can damage the sockets or the connect-
ed cables and/or their clamps.
If your power unit is not required, disconnect it from the mains.
Connecting the power cable
Connect the supplied grounding mains cable to the low-power device installation socket (27) on the pow-
er unit. Ensure a tight fit.
Connect the power cable to a shockproof mains socket with protective grounding.
Unit installation
Place the laboratory power unit on a stable, level and robust surface. Make sure that ventilation slots in
the casing are not covered up.
The front feet of the device can be unfolded for easier reading of the displays. They allow you to put the
laboratory power unit into a tilted position.
