SITOP PSE200U 3 A selectivity module 4-channel Input: DC 24 V/12 A Output: DC 24 V/4x 3 A Threshold adjustable 0.5-3 A with collective signaling contact The SITOP PSE200U selectivity module is the ideal addition to all 24 V power supplies to divide the load current between several current branches and monitor it. Overload and short circuits in one or more branches are reliably detected. The electronics allow short-term current peaks, e.g. due to high inrush current, and switches branches with longer overloads off. This is ensured even on high-impedance lines and in the event of creeping short circuits. The intact branches continue to be supplied with 24 V with absolutely no interruption or feedback, thus minimizing system downtimes. The faulty branch is signaled via LEDs on the device and via a collective signaling contact. No matter what industry, no matter what requirement - Siemens offers reliable and efficient power supplies for every system.
