Operating instructions
Intended Use
The laboratory power supply unit serves as a potential-free DC voltage source to operate low-voltage con-
sumers. It has two adjustable independent outputs. When switching the outputs of several power supply
units in series, voltages of >75 V/DC may be generated, which are dangerous to touch. From this voltage
insulated lines/measuring cables must be used for safety reasons. The devices are connected via 4 mm
safety sockets.
The output data of the laboratory measuring devices is as follows:
Item name
Output A
Output B
VSP 1220
0.1 - 20 V/DC
0.1 - 6 V/DC
0.1 - 20 A
max. 1.5A
VSP 1410
0.1 - 40 V/DC
0.1 - 6 V/DC
0.1 - 10 A
max. 1.5A
VSP 1605
0.1 - 65 V/DC
0.1 - 6 V/DC
0.1 - 5 A
max. 1.5A
The voltage and electric current for output A and the voltage for output B can be adjusted continuously. The
voltage and current values of output B are displayed via the push of a button on the display of output A.
The settings for current and voltage are made via coarse and fine controls in order to allow fast and pre-
cise value settings. The values are displayed on a clear display.
The output voltage of output A can be set through an external voltage and kept absolutely stable and
load independent using the sense function.
The current limitation for the constant current mode can be pre-set at the touch of a button. A shorting
bar at the output is not necessary during setting.
The device is overload and short-circuit-proof and contains a safety temperature cut-off.
The laboratory power supply is designed in compliance with protection class 1. It is only approved for con-
nection to shockproof sockets with protective grounding and an alternating current of 230V/AC commonly
used in households. The ground potential socket is directly connected with the protective earthing on the
mains plug.
Operation under adverse environmental conditions is not permitted. Unfavourable ambient conditions are:
-
moistness or high humidity
-
dust and combustible gases, vapours or solvents
-
Thunderstorms or similar conditions such as strong electrostatic fields etc.
