SITOP PSE200U 3 A NEC CLASS 2 Selectivity module 4-channel input: DC 24 V/12 A output: 24 V/4x 3A NEC class 2 Level adjustable 0.5-3 A with common signaling contact 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 signaled using LEDs and a group signal contact. The outputs meet the requirements of NEC Class 2. Regardless of the industry or requirements, Siemens offers reliable and efficient power supplies for every plant.
