Electronic Pumps Three Phase Protection Relay 5 LEDs For Status Indication

Phase sequence protector is a multi-function three-phase power system or three-phase power equipment monitoring and protection equipment.
The phase sequence protector can display the three-phase power supply voltage in real time, and can output through the relay when the power supply overvoltage protection, undervoltage protection, phase loss protection, unbalance protection, fault phase protection, PTC temperature protection, load side protection and other faults occur. The form provides the user with an alarm output and the contact control signal output by the protection circuit action, which functions as an alarm and protection. 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 ultra-wide temperature Chinese liquid crystal, with full-featured, stable performance, intuitive display, easy operation.
