The SolaHD SDN-C RED Redundancy Module Power Supply continually monitors the condition of two power supplies connected to a single load. If one power supply fails, the RED module automatically changes over to the other power supply.

The MOSFET design for the RED modules generate less heat than traditional diode-based designs. Less heat translates to longer life of the components that are housed in the same enclosure as the RED module, and a more compact design of the RED module itself, saving on panel space.

Diagnostic LEDs assist in balancing the load between the two power supplies during normal operation, extending the life of both power supplies. Output status information can be easily provided to a PLC or other control equipment, using the RED module’s relay output contact.

Extensive certifications mean the RED modules are suitable internationally, for harsh industrial environments and even hazardous locations. The RED module works with SolaHD SDN-C and SDN-P Series power supplies, as well as most power supplies capable of parallel operation.
