Redundant power supply module 12V 20A ERDN20-12

Redundant Power Module – Reliability and Protection for Your System

The ERDN20-12 redundant power module from MEAN WELL is a key element ensuring the continuity of power systems. The device is designed to operate in 5V, 12V, 24V and 48V systems, offering 1+1 or N+1 redundancy. The construction based on MOSFET transistors instead of traditional diodes translates to higher efficiency and lower energy losses. This module is an ideal solution for both professional installers and end-users who value stable and safe power supply.

Construction and Application

The ERDN20-12 module allows you to connect multiple power supplies to create a redundant system. In the event of a failure of one of the power supplies, the module automatically switches to the second, ensuring uninterrupted power to critical devices. This minimizes the risk of downtime and potential losses resulting from power outages. Failure signaling via relay connectors and LEDs facilitates quick problem identification and efficient diagnostics. Designed to operate in a wide temperature range – from -40°C to +80°C (with derating above +60°C) – making it suitable for use in harsh environmental conditions.
