Field of application

The common power supply (GSV) is an AC/AC converter that converts an alternating voltage
into a square-wave voltage. You can select one of the following rated voltages with associated
rated frequencies for the alternating input voltage:
● 1-phase 115 VAC / 60 Hz
● 1-phase 230 VAC / 50 Hz / 60 Hz
● 1-phase 240 VAC / 50 Hz / 60 Hz
On the front panel of the device there is a labeled switch with which the rated voltage can be
selected with the aid of a screwdriver. The square-wave voltage of 55 V generated from the
input voltage supplies four power outputs with equality of access. The design principle differs
according to which electronic component is to be supplied with the aid of the GSV.
Each power output is monitored for undervoltage. When the voltage level of all power outputs
is within the standard range, the LED signaling the status indication lights up green. The device
switches itself off automatically in the event of a short-circuit at one of the power outputs. The
associated LED of the affected power output lights up red until the short-circuit has been
rectified and the device is back in proper working order. This requires that the upstream
miniature circuit-breaker is opened and after approximately 10 seconds is closed again.
