20A Redundancy module for 48V systems

ERDN20 series is a 20A redundancy module that can be used with a power supply to improve overall system operation reliability. The MOSFET technology implemented can reduce heat loss and reduce the voltage difference between the input and output voltages. Built-in 2 channels DC OK relay contacts for monitoring output status.
