Redundant power supply module 48V 40A DRDN40-48

Redundant Power Supply Module 48V 40A – Increase System Reliability

This redundant power supply module, designated DRDN40-48, is a key element in building reliable power systems. It enables 1+1 or N+1 redundancy configuration, ensuring continuous operation even in the event of a power supply failure. This is particularly important in applications where a power outage can lead to serious consequences.

The DRDN40-48 module is designed to work with power supplies with voltages of 12V, 24V or 48V, offering flexibility in component selection. The output current of up to 40A allows you to protect a load with significant power. The design based on MOSFET transistors instead of traditional diodes minimizes energy losses and limits the voltage difference between input and output, which translates to higher system efficiency.

Construction and application

The module is characterized by compact dimensions (55x125.2x100mm) and convection cooling, which facilitates installation and integration in various applications. A wide operating temperature range (-40°C to +80°C, with derating above +60°C) allows it to be used in harsh environmental conditions. Built-in DC OK alarm contacts and relays inform about the output status and any failures, enabling a quick response and minimizing downtime.

The DRDN40-48 module finds application in:

• Uninterruptible Power Supply (UPS) systems
• Monitoring and security systems
• Industrial automation
• Telecommunications equipment
• Applications requiring high power supply reliability
