Description
The DRDN40 series is a 40A 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 (55mm).

NOTE |
1. All parameters NOT specially mentioned are measured at normal input(12V/24V/48V) , rated load and 25℃ of ambient temperature.
2. Derating may be needed over high ambient temperature. Please check the derating curve for more details. 3. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft). 4. The power supply is considered as an independent unit, but the final equipment still need to re-confirm that the whole system complies with the EMC directives. For guidance on how to perform these EMC tests, please refer to “EM testing of component power supplies.” (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf ) ※ Product Liability Disclaimer：For detailed information, please refer to https://www.meanwell.com/serviceDisclaimer.aspx |

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 DRDN40 to reduce the stress of the and hence increase the reliability MOSFET
