General
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 advantage of high stability, high over load capability, low power loss and small volume.
Basic Function
Mechanical step register or LCD display
Bi-directional total active energy measurement, reverse active energy measure in the total active energy
Pulse LED indicates working of meter, Pulse output with optical coupling isolation
Loss phase LED indication, Reverse connection LED indication
For LCD display type meter, Energy data can store in memory chip more than 15 years after power off
35mm din rail installation
