SDN-C Redundancy Modules
SolaHD SDN-C Redundancy Modules (RED) provide a common DC voltage feed from 2 connected power supplies to enable either high reliability or high power sourcing solutions.

As a redundant solution, the RED module continually monitors the condition of its two connected power supplies, and seamlessly migrates power draw from a failing supply to its counterpart. In a high-power solution, a RED module will feed up to the full capacity of both connected supplies to meet high demand conditions.

RED modules have low heat output thanks to MOSFET design. This extends useful life and reduces package size to improve control panel footprint and thermal impact. Diagnostic LEDs facilitate adjustment to equalize power draw across the connected power supplies. A relay output indicating status of the DC power can connect to an external controller to ensure synchronized operation.

Extensive certifications ensure RED modules comply to domestic and international safety standards, including application in many explosion-safe locations. RED modules support SolaHD SDN-C, SDN-D, and SDN-P power supplies, as well as 3rd party supplies capable of parallel operation. For redundant applications, choose the model that meets the load current requirement. For design assistance in high power applications, please contact SolaHD Technical Services.
