RPS – Redundant Power Selector

Specialist power changeover unit designed to protect 24 VDC supplies to critical components. Cyber Security certified.

The RPS, Redundant Power Selector has been designed specifically to protect critical componets during failure of a primary DC power supply.

The unit, which has a continuous capacity of up to 16 A, rapidly changes from a primary to a secondary power source once the primary voltage falls to a predetermined level. Why is this important? Many critical pieces of electronic equipment (such as engine ECMs) are sensitive to transient low voltages. Unless the power is transitioned quickly and smoothly, there is a risk of these components switching off momentarily.

The RPS ensures a safe and reliable handover with built-in smoothing circuits. Two status outputs—Primary OK and Secondary OK—enable external systems to monitor or respond to the state of each input power source.

Cyber Security certified.
