Power quality monitoring deviceWhat are the characteristics?
1. Equipped with GPRS wireless transmission function and Ethernet remote transmission function, real-time data of each monitoring point can be obtained anytime and anywhere. Through remote control technology, it is possible to modify and set any monitoring point at any time and perform special tests.
2. You can view the data recorded by ZS3590 anywhere and at any time, and conduct detailed and in-depth analysis on the upper computer.
3. If there is an abnormal power event, ZS3590 can provide an alarm prompt at a faster speed, and through the original data, the equipment number and location of the problem can be quickly identified on the computer.
4. Built in large capacity Flash storage disk, ensuring the length of recording time and the integrity of recorded data.
5. Measurable range
