DC-UPS systems can be easily set up when this module is combined with CC/CV-constant DIN rail power supplies and a rechargeable battery. A power supply with an output voltage of 27.6 V (end-of-charge voltage of the rechargeable battery) and a lead-gel battery are connected to the DC-UM 22. The total of the load current and charging current must not exceed 20 A. The DC-UM 22 is equipped with a battery fuse that protects the rechargeable battery and battery cable from polarity reversal. 'Mains' and 'rechargeable battery' mode are signalled by LEDs. As a potential free changeover contacts, a network failure report or a U-Min report are available. The rechargeable battery is automatically disconnected at approx. 19 V before the deep discharge protection threshold is reached.
