DC-UPS systems can be easily set up when this module is combined with CC/CV-constant DIN rail power supplies & a rechargeable battery. A power supply with an output voltage of 27.6V (end-of-charge voltage of the rechargeable battery) & a lead-gel battery are connected to the DC-M 22. The total of the load current & charging current must not exceed 20A. The DC-M 22 is equipped with a battery fuse that protects the rechargeable battery & battery cable from polarity reversal. Mains & 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. 19V before the deep discharge protection threshold is reached. Technical data: Input voltage 27.6V. Maximum Current 20A. Weight: 0.2kg.
Dimensions (W x H x D): 130 x 98 x 60 mm. Type: DC-M 22.
