The DRDN40 series is a 40A redundancy module that can be used with a power supply to improve overall System opération reliability. Product key features include:12V/24V/48V input voltage for selection, support N+1 and 1 + 1 redundancy Systems,built-in two rails DC input contacts and single output. 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, ultra-wide operating temperature of -40 to +80°C and narrow width (55mm).
