Siemens Selectivity Module, for use with SITOP, PSE200U Series

SITOP PSE200U Selectivity Module

The SITOP PSE200U selectivity module is the optimal addition to all 24 V power supplies for distributing and monitoring the load current across several branch circuits. Overload and short-circuit in one or more feeders are reliably detected.
The electronics tolerate short-term current peaks, e.g. due to high inrush current, and de-energize feeders with longer overload. This is ensured even on high-resistance cables and for short-circuits that develop slowly over time.
The intact feeders continue to be supplied with 24 V without any interruption or disturbance, thereby minimizing plant downtimes. The faulty feeder is signalled using LEDs and a group signal contact. Regardless of the industry or requirements, Siemens offers reliable and efficient power supplies for every plant.
