Product Details

Pumps Three Phase Voltage Monitoring Relay , AVM-N Phase Detection Relay 460VAC

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

can be output through the relay when a power supply overvoltage protection, undervoltage protection, phase loss protection, unbalance protection, fault phase protection, load side protection, etc.

The user provides the contact control signal output by the alarm output and protection circuit action, and plays the role of 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.
