Description
The DRDN20 series is a 20A redundancy module that can be used with a power supply to improve overall system operation 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 (32mm).

Typical Application Notes
- 1+1 Redundancy:
Using 1 more PSU as the redundant unit
- 1+N Redundancy:
Using more PSUs as the redundant units to increase the reliability
- Single Use:
Connecting only one PSU to one DRDN20 to reduce the stress of the MOSFET and hence increase the reliability.
