The three-phase power is sampled and processed. When the phase sequence of the power phase and the phase sequence input by the protector terminal match, the output relay is turned on, and the main control loop of the device is turned on. The existing two types of products are: when the phase sequence of the power supply changes, the phase sequence does not match, the output relay cannot be connected, thereby protecting the equipment and avoiding accidents; the other type adopts digital micro-core technology products, which can realize automatic Phase sequence identification and automatic phase sequence conversion to ensure constant phase rotation of the motor. .

GINRI POWER AUTOMATION CO.,LTD. is a professional production voltage phase sequence protection device (and name: three-phase power monitor), and PLC output zoom Board, and smart type motor integrated protection device, and industrial parts manufacturers, technology development team in elevator industry, and refrigeration industry, and crane industry, environmental equipment, mechanical NC industry and the industrial following insurance industry, field has more than 10 years practice experience, has development out variety price economic and function excellent of products.
