Crestron DIN-PWR-RD – DIN Rail Redundancy Module

Product Overview

The Crestron DIN-PWR-RD is a DIN rail-mount power supply redundancy module that allows two DIN rail power supplies to operate in parallel, with automatic failover if one supply fails. In mission-critical Crestron control installations—such as commercial buildings, boardrooms, and facilities that require continuous operation—the DIN-PWR-RD provides N+1 redundancy for the DIN rail power infrastructure, ensuring the control system remains operational if a primary power supply fails.

Product Description

Power supply redundancy is a requirement in any control system where downtime is unacceptable. Boardrooms, security systems, critical infrastructure, and commercial AV installations often specify redundant power to guarantee that the control system will not fail if a single power supply experiences a fault. The DIN-PWR-RD installs on the DIN rail alongside the power supplies it protects and manages current sharing and failover switching automatically—no manual intervention is needed when a supply fails or when the system is restored. The DIN rail form factor allows it to be installed within the same panel enclosure as the power supplies and other Crestron DIN modules, keeping all power infrastructure in a single organized location. Proper power supply redundancy also extends the lifespan of individual power supplies by sharing the load between two units during normal operation.

Frequently Asked Questions

Q: How many power supplies does DIN-PWR-RD support?
A: The DIN-PWR-RD supports two power supplies in a redundant configuration. Consult Crestron product documentation for specific compatible power supply models and current capacity specifications.

Q: Is manual switchover required when a power supply fails?
A: No. The DIN-PWR-RD handles failover automatically. When the primary supply fails, the secondary supply takes over without requiring any manual intervention.
