## Long description

The MEAN WELL DUPS20 is a 24V DC-UPS module for DIN-rail or wall mounting that provides uninterrupted DC supply to connected loads by switching to an external battery pack when input power is lost.

Its compact housing (40mm wide) and lightweight construction make it suitable for installations with limited space.
