User manual

The following parameters can be adjusted:

Output voltage „Uo“, voltage limitation „Umax“, current limitation „Imax“, capacity limitation „Pmax“. The

output can be switched off with the push of a button. The operating elements can be blocked to prevent

wrong operation.

Via a serial interface (RS232C), the laboratory power supply unit can be additionally controlled and

adjusted via a PC.

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

connection to a mains socket with protective earthing and a normal AC voltage of 230V 50Hz. The

ground potential socket is directly connected with the protective earthing on the mains plug.

Do not use in adverse ambient conditions. Unfavourable ambient conditions are:

- damp or excessively high air humidity

- dust and combustible gases, vapours or solvents

- thunderstorms or similar conditions such as strong electrostatic ﬁelds etc.

Any use other than the one described above damages the product. Moreover, this involves dangers such

as e.g. short circuit, ﬁre, electric shock, etc. No part of the product must be modiﬁed or rebuilt! Please

read the operating instructions thoroughly and keep the operating instructions for further reference.
