Voltage Monitoring Relays - Monitored voltage range - 3 x 144 - 276 V AC
We supply a wide range of relays for voltage and monitoring in 1-phase, 3-phase, AC and DC networks. Simple, 1-module designs perform basic functions, and 3-module designs for more accurate measurements in multiple ranges with galvanic separation of power supply from the measured circuit.
The relay monitors undervoltage, sequence and phase failure
