Redundant power supply module 12V 40A DRDN40-12

Redundant Power Module – Reliability and System Protection

This redundant power module, designated DRDN40-12, is a key element ensuring the continuity of power systems. Designed for DIN rail mounting, it enables the creation of a redundant power configuration, 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 the stability and safety of powered devices.

Construction and Application

The DRDN40-12 module is designed to operate in 12V DC systems, offering an output current of up to 40A. Its construction based on MOSFET transistors instead of traditional diodes increases energy efficiency and reduces heat loss. This makes it possible to connect multiple power supplies to achieve redundancy, meaning that if one of them fails, the system will continue to operate without interruption. A wide operating temperature range (-40°C to +80°C with derating above 60°C) allows it to be used in demanding environmental conditions. Relay connections and LEDs indicate the system's operating status – indicating a possible failure of the primary or backup power source.

Key Features and Benefits

• Redundancy: Provides uninterrupted power to critical devices thanks to the ability to connect multiple power supplies in a redundant configuration (1+1 or N+1).
• High Efficiency: The use of MOSFET transistors minimizes energy loss and improves system efficiency.
• Wide Input Voltage Range: Compatible with 12V DC systems.
• Status Indication: Built-in LEDs and relays indicate the system's operating status (failure of primary/backup source).
• DIN Rail Mounting: Facilitates installation and integration with existing systems.
• Durability: Operation in a wide temperature range (-40°C to +80°C) guarantees reliability even in harsh conditions.
• Compact Dimensions: 55x125.2x100mm allow for easy adaptation to limited space.
• 3-Year Warranty: Confirms the high quality of the product and ensures peace of mind.

The DRDN40-12 module is characterized by an output voltage of 12V, an output current of up to 40A, and a maximum reverse voltage of 60V. Its dimensions are 55x125.2x100mm.

The DRDN40-12 module is an investment in the stability and safety of your power system – regardless of whether you are a professional installer or an end-user looking for a reliable solution.
