ENC 1725 REDUNDANT POWER SUPPLIES

Description

Encore manufactures a complete line of Redundant Power Supplies for critical applications, where a loss of power for any length of time is not an option.  Our power supplies are known world wide for their performance and reliability. Each redundant supply is designed with diodes to isolate one supply from the other and to prevent shorting of the output or current from flowing back into the other supply. Built-in circuit breakers protect both the primary and redundant supply. At Encore, we can design a redundant power supply to meet your specific power requirement, whatever it may be.

All redundant power supplies are packaged in a convenient rack mount or table top chassis based on your specification.

Call Encore today to discuss your specific requirements for a reliable power supply.

Rear Panel

ENC1725 Rear Panel

Independent 20A, Front Panel, Circuit-Breaker Switches for Primary and Redundant circuits. Breakers are independently actuated to verify redundancy is operational.

Internally, there are two duplicate supplies per output. The supply closer to the front panel is the Primary, while the supply closer to the rear panel is the Redundant.
