ASJ50-GQ voltage monitoring device for air conditioning compressor
- Jiangsu Acrel Electrical Manufacturing Co.,LTD.


  • ASJ50-GQ air conditioning compressor voltage monitoring device (hereinafter referred to as the monitoring device), suitable for single-phase AC voltage 220V, frequency 50Hz/60Hz users or load. When the line occurs over, under voltage, monitoring device to protect the equipment. The monitoring device integrates the functions of over-voltage, under-voltage protection and automatic delay reset of normal voltage. Small size, high precision, compact structure, easy installation.

    Product features

    Built in high performance processor, high reliability, strong anti-interference ability.

    When overvoltage or undervoltage occurs, the line will be cut off, and the line voltage will return to normal. After delay, the line will be automatically reset and connected without manual operation.

    The frequency is 50 Hz / 60 Hz, and the power consumption of the product is not more than 2 VA.

    Electrical life: 10000 times.

    Aperture installation.
