        本產品是一種智能多功能監(jiān)測和保護儀器，集計時計次功能和電壓顯示、過欠壓保護、缺相保護、相序保護于一體采用功能*的微處理器芯片和非易失存儲技術，中文液晶顯示，顯示直觀、操作簡便?？捎涗浌ぷ鲿r間、工作次數(shù)故障時間故障次數(shù)等運行參數(shù)，實時顯示電源電壓，并在三相電源發(fā)生過壓、欠壓、缺相、錯相等故障時自動切斷電源，起到很好保護作用。

        適用于空調、起重機、制冷設備、壓縮機、配電箱、升降機、各種客、貨電梯、吊車、行車、機床等頻繁啟動設備進行實時監(jiān)控和保護，正確累計設備啟動次數(shù)和運行時間。同時能對設備的供電源進行監(jiān)控，在電源發(fā)生異常時切斷電源，并記錄電源發(fā)生故障的次數(shù)和累計時間。

        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.
