Redundant power supply module 12V 40A ERDN40-12

Redundant power supply module – reliability and protection for your system

This redundant power supply module, designated ERDN40-12, is a key element ensuring continuous operation in systems requiring high availability. It allows you to connect multiple power supplies to create a redundant system, minimizing the risk of downtime caused by the failure of one of the power supplies. This solution is ideal for both professional installers and end-users who value stability and power security.

Construction and application

The ERDN40-12 module is designed to operate at 12V and a current of up to 40A. It uses MOSFET transistors instead of traditional diodes, which translates to higher energy efficiency and lower heat loss. This makes the device more efficient and reliable. It can be used in 5V, 12V, 24V and 48V systems, offering a wide range of applications. Failure signaling of the primary and backup power systems is done using built-in relay connectors and LEDs, which facilitates diagnostics and quick response in case of problems.

Key features and benefits

• Redundancy: Provides uninterrupted power by automatically switching to backup power in the event of a main power failure. This is especially important in critical applications where even a short power interruption can cause serious losses.
• High efficiency: The use of MOSFET transistors minimizes energy loss and generated heat, which translates to a longer device life and lower operating costs.
• Wide voltage range: Compatibility with 5V, 12V, 24V and 48V systems makes the module universal and can be used in various applications.
• Failure signaling: Built-in relays inform about power problems, enabling quick response and minimizing downtime.
• Wide operating temperature range: The device maintains full functionality in a temperature range of -40°C to +80°C (with derating above +60°C), making it an ideal solution for industrial applications and in harsh environmental conditions.
• Compact dimensions: Dimensions of 97x99x36mm allow for easy integration of the module into existing systems without taking up much space.

The ERDN40-12 module is an investment in the stability and reliability of your power system. Its solid construction and advanced features make it an ideal solution for demanding industrial applications, server rooms and other places where continuous operation is a priority.
