DRDN-20/40 & ERDN-20/40 Redundancy Modules

MEAN WELL DRDN-20/40 and ERDN-20/40 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 within an ultra-wide -40°C to +80°C temperature range. The DRDN-20/40 and ERDN-20/40 modules are suitable for semiconductor process equipment, industrial control, factory automation, and electromechanical equipment.
