A monitoring relay is a protection device for phase and voltage monitoring of power system or equipment. ATO as a vendor offers high quality single phase voltage, 3 phase voltage, DC coltage monitoring relay and SPDT DIN rail mount phase failure relay. 12V, 24V, 36V, 48V, 110V and 240V rated voltage can be chosen. Monitoring relay with LCD display and keypad afford precise digital setting. Voltage monitoring relay provides reliable relay protection for motors, pumps, fans, cranes, blowers, elevators, power distribution cabinet, air-conditioning system and so on.
Single Phase Monitoring Relay
Single phase voltage monitoring relay is suitable for undervoltage and overvoltage, compact size relay with 1 CO & 1 NC contacts. It can be used in the electric motors and pumps.
3 Phase Voltage Monitoring Relay
3 phase voltage monitoring relay is used to monitor phase loss, phase sequence and voltage unbalance. Overvoltage and undervoltage in the 3-phase power supply of 208-480V AC 50 / 60Hz.
DC Voltage Monitoring Relay
DC voltage monitoring relay is applied in the DC circuit for monitoring undervoltage and overvoltage of DC cabinet and battery. Relay with 2 C/O contacts provide protection for the equipment.
SPDT DIN Rail Mount Phase Failure Relay
DIN rail mount phase failure relay with SPDT (1 C/O) contact, performs the monitoring functions including phase loss and phase sequence in the 3 phase AC power system.
