The SITOP SEL1200 selectivity module is the optimal addition to all 24 V power supplies for splitting and monitoring the load current on several current branches. Overload and short-circuit in one or more branches are reliably detected. Short-term current peaks, such as those caused by high inrush current, are allowed by the electronics; branches with longer overloads are de-energised. This is ensured even on high-impedance lines and with creeping short circuits. The intact feeders are supplied, thus minimising system downtimes. The faulty branch is signalled via LEDs on the unit as well as via a group signal contact or diagnostic monitor. Regardless of the industry and requirements, Siemens offers reliable and efficient power supplies for every system.
