Intended Use - VOLTCRAFT HPS-11530 Mode D'emploi

3. Intended use

The laboratory power unit serves as a potential-free DC voltage source to operate low-voltage consumers. The adjust-
able output can be tapped with up to 5 A at the front and up to the full nominal current at the back. The front output is
limited to 5 A and protected against overload. When switching the outputs of several power supplies in series, voltages
of >75 V/DC, which are dangerous to touch, may be generated. This is why insulated lines/measuring cables must
be used for safety reasons for voltages above this. Connection on the front is performed with 4 mm safety sockets,
on the back with high-current socket screw connectors. The outputs (front and back) are connected to each other.
The connection cables used must be large enough. Where the conductor section is too small, overheating
and fire may result.
The output data of the laboratory measuring devices is as follows:
Type
HPS-11530
HPS-11560
HPS-13015
HPS-13030
HPS-16010
Current and voltage can be set continually through digital rotary controls using coarse and fine settings in order to
allow fast and precise value settings. The values are displayed on the structured LC display. A power limit for constant
power operation can be pre-set without a shorting bar.
The power unit can be remote-controlled An external voltage (0 - 5 V/DC) or external potentiometer (5 kOhm) can
be used to set the output voltage and output current. The DC output is turned on and off via the a switching contact.
Model HPS-11560 also has a remote sensor function (SENSE). The voltage drop in case of high load currents can
be compensated for this way. The output voltage at the consumer remains absolutely stable and independent from
the load.
Three freely programmable memory slots can be assigned to different fixed voltages and current limitations. The
selection switch is located at the back of the device.
The device is overload- and short-circuit-proof and contains a safety temperature cut-off.
The laboratory power unit is designed in compliance with protection class 1. It is only approved for connection to
shockproof sockets with protective grounding and an alternating current of 230V/AC commonly used in households.
The mains socket must be located close to the device and easily accessible, or an emergency stop fixture must be
available.
Operation under adverse environmental conditions is not permitted. Unfavourable ambient conditions are:
- moisture or high humidity
- dust and combustible gases, vapours or solvents
- thunderstorms or similar conditions such as strong electrostatic fields etc.
It is intended for indoor use only. Do not use it outdoors. Contact with moisture, e.g. in bathrooms, must be avoided
under all circumstances.
