Field of application
The common power supply (GSV) is an AC/AC converter that converts an alternating voltage
into a square-wave voltage.
The square-wave voltage of 55 V generated from the input voltage supplies four power outputs
with equality of access.
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.
