The meter is used in three phase four wire/three phase three wire/two phase three wire power grid. The meter is designed to measure AC active energy. It is a long life meter with the advantages of high stablity, high over load capablity, low power loss and small volume.
1. Mechanical step register or LCD display
2. Bi-directional total active energy measurement, total active energy reverse active energy measurement
3. Pulse LED indicates working of meter, Pulse output with optical coupling isolation
4. Loss phase LED indication, Reverse connection LED indication
5. For LCD display type meter, energy data can store in memory chip more than 15 years after power off
6. 35mm din rail installation
