Intended Use; Control Elements - VOLTCRAFT SPS12/120 Bedienungsanleitung

Intended use

The power supply unit is designed to connect and operate low voltage consumers
with an operating voltage of 13.8 V DC. The voltage is taken from the two high cur-
rent screw-type jacks on the back.
The power supply unit supplies a current of up to 120 amperes. The power con-
sumption of a connected consumer may not exceed this limit.
To compensate for line losses, a "SENSE" cable must always be connected.
The output is short-circuit protected and resets the output power in case of a short
circuit.
The DC connection cables must have a large enough conductor cross-section for
the corresponding current consumption. If the conductor cross-section is too small,
there is a risk of fire. For the rated current (120 A), the cross-section of the conduc-
tor must be 35 mm .

The switching power supply is designed in compliance with Protection Class 1. It is
only approved for connection to sockets with protective earthing contact and an
alternating current of 230 V~/50 Hz, commonly used in households.
Operation in unfavourable ambient conditions is not permitted. Unfavourable
ambient conditions include the following:
- Excessive moisture or humidity
- Dust and combustible gases, vapours or solvents
- Electrical storms or stormy conditions resulting in strong electrostatic fields, etc.
Any use apart from the use described above will damage the product and may invol-
ve other risks, such as short circuit, fire, electric shock, etc. Do not open, change or
modify any part of the product. The safety instructions should be observed without
fail.

Control elements

(see fold-out page)
(1) Power switch to start the device (I = ON / O = OFF)
(2) Green display indicating operating mode
(3) Red display indicating an overload
(4) Control with cover to set the DC output voltage
(5) Inlet connector with earthing contact for cooling apparatus
(6) Fan opening for cooling the device
(7) Screw-type jack for high current output, "negative pole"
(8) Screw-type jack for high current output, "positive pole"
(9) "SENSE" connection for automatic correction of the voltage at the high current
output
