DURAmax DC-UPS 24V 5A UPS Module
Ask an expert!
The Weidmüller DURAmax DC-UPS 24V 5A is a compact, DIN-rail mounted uninterruptible power supply module for 24VDC industrial control systems. When mains power fails, the DURAmax bridges the gap instantly — keeping PLCs, sensors, and critical loads running without interruption. With support for lead-acid VRLA batteries from 1.2Ah to 100Ah and configurable via USB-C, it is the logical upgrade from any existing 24VDC UPS control module in service today. Made in Germany, CRA Ready, and certified to CE, UL, and DNV standards.
