PULS UB10.241 DC UPS Control Unit, 24 VDC, 20 A, DIN-Rail

The PULS UB10.241 is a DC UPS control unit that ensures uninterrupted 24 VDC power for critical loads by seamlessly switching to battery backup during mains failure. It supports lead-acid batteries from 3 Ah to 130 Ah and delivers up to 20 A output current.

Advantages

High efficiency up to 99.3% minimizes heat generation and energy loss. Selectable charging current (2 A, 5 A, or 10 A) allows adaptation to different battery sizes. Comprehensive protection features include reverse battery polarity, short-circuit, over-temperature, and over-voltage protection. Clear LED status indicators and relay contacts provide real-time system monitoring.
