Phase Sensors and Phase Sequence Relays

Protect aircraft equipment & other devices from damage due to phase loss or reversal with DARE's phase sensors & monitors. Designed to monitor the phase sequence of three phase power, DARE's phase sensors will protect electrical equipment that is sensitive to incorrect phase sequence (rotation), phase loss, or phase reversal. When the phase rotation is correct, the output of DARE's phase sensor will energize. When the phase sensor detects an out-of-phase condition, the output will de-energize. The contacts of the phase sensor can be used to disconnect a load, operate an alarm circuit, or both.
