DBUF20/40 DIN Rail Buffer Modules

MEAN WELL DBUF20/40 DIN Rail Buffer Modules can be used with DIN rail power supplies to provide short-term backup for the load. The units enter the buffer mode when the AC mains power is temporarily suspended or interrupted. The function offers stable 24V_DC to extend the system operation time, and the buffer time depends on the load current. MEAN WELL DBUF20/40 DIN Rail Buffer Modules can sustain a 20A load for 350ms and a 40A load for 250ms.
