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 Threshold adjustable 0.5-3 A with collective signaling contact 'The SITOP PSE200U selectivity module is the optimal addition to all 24 V power supplies in order to divide the load current between several current branches and to 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 switch branches with longer overloads off. This is ensured even on high-impedance lines and in the case of creeping short circuits. The intact branches continue to be supplied with 24 V without interruption or feedback, thus minimizing system downtimes. The faulty branch is signaled via LEDs on the device and via a common signaling contact. The outputs meet the requirements of NEC Class 2. No matter what industry, no matter what requirement - Siemens offers reliable and efficient power supplies for every system.'

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 switch off branches with longer overloads. 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 without interruption or feedback, thereby minimizing system downtime. The faulty branch is signaled via LEDs on the device and via a collective signaling contact. The outputs meet the requirements of NEC Class 2.
