CP DC-UPS 24V 40A UPS Module
Ask an expert!
The Weidmüller CP DC-UPS 24V 40A is the high-current model in the CP DC-UPS range, designed for 24VDC control systems with larger continuous loads. In normal operation the input voltage passes directly through to the load. On mains failure the system switches instantly to battery operation, keeping PLCs, sensors, and critical loads running without interruption. Three relay outputs and three active transistor outputs provide full remote monitoring and control via PLC or DCS. Compatible with Weidmüller CP A Battery modules from 3.4Ah to 17Ah, with buffer times selectable from 30 seconds to indefinite via front-panel rotary switch.
