RPS – Redundant Power Selector

Specialist power changeover unit designed to protect 24V DC supplies to critical components.

SKU: 1311229

  • Specifications

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

    The unit, which has a continuous capacity up to 16A, 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 electronics (such as engine ECM’s) are sensitive to transient low voltages. Unless the power is transitioned quickly and smoothly there is a risk of those components switching off momentarily. The RPS changes far more quickly than a mechanical relay, and with the inbuilt added smoothing circuits, it ensures a safe, reliable hand over. The RPS also provides an indication to show the status of each power supply connection and supply for 3rd party connection so operators are always aware of the power status to these critical pieces of equipment.
