Functional Description - VOLTCRAFT HPS-11530 Bedienungsanleitung

Do not switch the laboratory power pack unit on immediately after it has been taken from a cold to a
warm environment. Under adverse conditions, the resulting condensation could destroy the device.
Allow the device to reach room temperature before switching it on.
The plug-in power unit generates heat during operation; ensure that it is adequately ventilated. Do not
cover the ventilation apertures of the device!
Never expose the device to any direct sunlight. Avoid heat sources in direct proximity. The device might
overheat.
Do not leave power units and connected consumer devices in operation unattended.
Do not place any containers filled with liquid, e.g. vases or plants, on or next to the power unit. If they fall
over, the device can be destroyed and there is a great risk of fire.
When working with power units, wearing metallic or conductive jewellery, such as necklaces, bracelets,
rings etc., is prohibited.
The power unit is not designed for attaching to humans or animals.
Never expose the device to mechanical stress. Dropping the device even from a low height may dama-
ge it! Avoid vibrations.
If you have reason to believe that the device can no longer be operated safely, disconnect it immediate-
ly and make sure it is not unintentionally operated. It must be assumed that safe operation is no longer
possible if:
- the device shows visible damage,
- the device no longer works and
- the device was stored under unfavourable conditions for a long period of time or
- after it was exposed to extraordinary stress caused by transport.
You should also heed the additional safety instructions in each chapter of these operating instructions as
well as in the operating instructions of the connected devices.

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 isolated and feature a protective isolation against the mains voltage. For the secondary
DC connection, there are two coloured safety sockets on the front (max. 5A) and two high-load terminal
screw clamps on the back (full nominal current range).
The structured display shows the voltage and current (V = Volt = unit of electric voltage, A = Ampere = unit of
electric current) and the status display in case of device interferences.
Various protective mechanisms, e.g. overload protection, current limitation, overheating protection, etc.
are built in for secure and reliable operation.
The power unit is cooled through a temperature-controlled fan. Therefore, ensure sufficient air circulation.
The output voltage and output current at the power unit are infinitely adjustable.
