MEAN WELL ERDN4024 40A Redundancy Module
The MEAN WELL ERDN40 series is a 40A redundancy module that can be used with a power supply to improve overall system operation reliability. Key features include 12V/24V/48V input voltage selection, support for N+1 and 1+1 redundancy systems, built-in two rails DC input contacts, and a single output. The MOSFET technology implemented reduces heat loss and the voltage difference between the input and output voltages. It also features built-in 2 channels DC OK relay contacts for monitoring output status and ultra-wide operating temperature.
