3Phase 3Wire AC Voltage Phase Sequence Protector, Model GS-AV3C1-JxMC-PSP
Phase sequence protector, also called phase sequence relay, is a kind of control relay. It can automatically identify the phase sequence to avoid some special mechanical and electrical equipment from accidents or equipment damage due to the reverse connection of power supply phase sequence (reverse connection of three live wires) and the reverse connection of motor.
GS-AV3C1 series are 3phase 3wire AC voltage phase sequence protector. The input voltages are collected, isolated and calculated and then output switch signals to detect and judge the voltage sequency state. The device adopts professional MCU and 24 bit high-precision A/D Processor to measure the electric voltage, which has the characteristics of high precision and good stability.
Power supply:12V DC 24V DC;
