Isolated DC/DC Converter - 40A, 48Vdc, Redundancy Module

MEAN WELL DRDN-20/40 and ERDN-20/40 Series Redundancy Modules are used with a backup power supply to improve overall system operation reliability. These modules feature 5V (ERDN20 only) /12V/24V/48V input voltage for selection support for N+1 and 1+1 redundancy systems built-in two rails DC input contacts and a single output. The DRDN-20/40 and ERDN-20/40 modules adopt MOSFET technology to reduce heat loss and the voltage difference between input and output voltages. These modules operate from -40°C to 80°C ultra-wide temperature range.
