1SVR427049R0000 ABB CP-D RU Redundancy Unit 2 x 5 A Input 10 A Output

Why Choose the ABB CP-D RU Redundancy Unit?

The ABB CP-D RU, order code 1SVR427049R0000, is a compact redundancy unit for ABB CP range power supplies designed to increase the availability and reliability of critical DC power systems. It decouples two power supply units, allowing an automatic redundant power configuration in which the remaining supply can continue powering the load if the other power supply fails.

The CP-D RU provides two input channels rated up to 5 A each and operates across a 9–35 V DC input range. It supports an output of up to 5 A in a true redundant configuration or up to 10 A when the two power supplies are combined for increased power.

Its 100% decoupling of two parallel-connected power supplies helps isolate the supplies from one another and supports dependable operation in applications where DC power availability is important. The modular DIN-rail component design makes the CP-D RU particularly suitable for compact installation in industrial control cabinets and distribution panels.

Improving DC Power Availability with True Redundancy

A true redundant DC power architecture uses two independent power supplies and a redundancy unit to help ensure that failure of one supply does not interrupt power to the connected load. The ABB CP-D RU decouples the two power supply channels and automatically supports continued operation from the remaining source, making it suitable for control systems where power availability is critical.

The CP-D RU can also be used to combine two parallel-connected supplies for increased output capacity. With each input channel capable of handling up to 5 A, the module supports up to 5 A for true redundancy or up to 10 A when configured for increased power, providing flexibility for industrial DC distribution designs.

Typical Applications

• Redundant 24 V DC industrial power systems.
• PLC and automation control cabinets.
• Machine control and production equipment.
• Critical instrumentation and monitoring systems.
• Process automation installations.
• Industrial control and communication equipment.
• Distribution panels requiring increased DC power availability.
• Parallel power supply configurations requiring electrical decoupling.
