Elevator Three Phase Voltage Monitoring Relay , Over and under voltage protection relay

The three-phase power protector is a multi-function three-phase power system or three-phase power equipment monitoring and protection equipment. Sets three-phase voltage display, over-voltage protection, under-voltage protection, phase loss protection (phase-failure protection), voltage imbalance protection, phase sequence protection (wrong phase protection) in one, using a powerful microprocessor chip and non-easy Loss of storage technology, display using high-definition wide temperature Chinese liquid crystal, with full-featured, stable performance, intuitive display, easy operation.

Three-phase power protector|Power protector can display real-time three-phase power supply voltage, can be over-voltage protection in the power supply, under-voltage protection, lack of phase protection, unbalance protection, phase fault protection and other failures through the relay output in the form of Users provide alarm output and protection circuit action output contact control signal, play alarm and protection
