        本产品是一种智能多功能监测和保护仪器，集计时计次功能和电压显示、过欠压保护、缺相保护、相序保护于一体采用功能强大的微处理器芯片和非易失存储技术，中文液晶显示，显示直观、操作简便。可记录工作时间、工作次数故障时间故障次数等运行参数，实时显示电源电压，并在三相电源发生过压、欠压、缺相、错相等故障时自动切断电源，起到很好保护作用。

        适用于中央空调、起重机、制冷设备、压缩机、配电箱、升降机、各种客、货电梯、吊车、行车、机床等频繁启动设备进行实时监控和保护，正确累计设备启动次数和运行时间。同时能对设备的供电源进行监控，在电源发生异常时切断电源，并记录电源发生故障的次数和累计时间。

        This product is a kind of intelligent multi-function monitoring and protection instrument, the set timing function and voltage display, undervoltage protection, missing phase.The protection and phase sequence protection is integrated with a powerful microprocessor chip and non-volatile storage technology, Chinese liquid crystal display, display straight.Easy to operate. It can record the operating parameters such as working time, number of failure times of working times and so on, and display the power voltage in real time.It can automatically cut off the power supply when the three-phase power supply has been overvoltage, undervoltage, lack of phase and fault, and it is very protective.

        Suitable for central air conditioning, crane, refrigeration equipment, compressor, distribution box, elevator, various passenger, cargo lift, crane,The equipment can be 

monitored and protected in real time by driving, machine tools and other frequent start-up equipment, and the number of equipment startup times and running time is correct. At the same time toThe power supply source of the equipment is monitored, the power supply is cut off when the power supply is abnormal, and the frequency and the cumulative time of the power failure are recorded.
