Phase Failure Relay
The Phase Failure Relay is a critical point of failure in any automatic power control system; if the relay itself fails, the system will act as if a real power failure has occurred, causing unnecessary interruption of the load. As the relay is connected to the supply for prolonged periods, and can be subject to power surges and harmonic distortions, failure often occurs, but the risk is normally accepted as being unavoidable, - until now....more

Configuration can be either as a change-over volt-free contact, to operate devices having a separate source of power, or the unit can be used to drive a coil or other device directly, using power from the Triplex system batteries, via the three input feeds.....more
