SolaHD SDN Redundancy Modules are designed for industrial applications where reliable DC control power is critical. These modules connect two compatible power supplies to a common DC load, helping provide redundancy, load sharing, and improved system availability in demanding automation and process control environments.
In a redundant configuration, the module monitors two connected power supplies and allows the system to continue operating if one supply fails. In high-power applications, redundancy modules can also support combined output capacity where appropriate. They are commonly used with SolaHD SDN-C, SDN-D, SDN-P, and other compatible power supplies capable of parallel operation.
The SolaHD SDN2X40RED SDN-C Redundancy Module combines two compatible DC power supplies into a common output for 40 Amps of redundant current or up to 80 Amps in non-redundant operation. Its low-loss MOSFET design, diagnostics and Vout OK relay support reliable industrial control power systems.
The SolaHD SDN2X10RED SDN-C Redundancy Module combines two compatible DC power supplies into a common output for 10 Amps of redundant current or up to 20 Amps in non-redundant operation. Its low-loss MOSFET design, diagnostics and Vout OK relay support reliable industrial control power systems.
The SolaHD SDN2X20RED SDN-C Redundancy Module combines two compatible DC power supplies into a common output for 20 Amps of redundant current or up to 40 Amps in non-redundant operation. Its low-loss MOSFET design, diagnostics and Vout OK relay support reliable industrial control power systems.
Redundancy modules are used when an industrial control system cannot afford to lose DC power from a single failed power supply. By connecting two compatible power supplies through a redundancy module, the system can continue feeding the load if one power supply drops out or requires service.
Choose an SDN Redundancy Module when your application requires higher reliability than a single power supply can provide. These modules are commonly used in control panels where downtime is costly, safety is important, or continuous operation is required.
