SolaHD SDN2X10RED SDN-C Redundancy Module 10A Redundant 20A Non-Redundant
The SolaHD SDN2X10RED provides a common DC output from two connected power supplies for high-reliability redundant operation or higher-current power sourcing. It supports up to 10 Amps in redundant operation and 20 Amps in non-redundant operation, with a low-loss MOSFET design that minimizes heat and supports seamless transfer between connected supplies.

SolaHD SDN-C Redundancy Modules provide a common DC voltage feed from two connected power supplies for high-reliability redundant operation or higher-current power sourcing. Their low-loss MOSFET design minimizes heat, reduces panel space requirements and supports seamless transfer from a failing supply to the remaining source.
Diagnostic LEDs assist with load balancing, while a normally open Vout OK relay can communicate DC power status to an external controller. The modules support SolaHD SDN-C, SDN-D and SDN-P power supplies, along with compatible third-party supplies capable of parallel operation.
