1.General Introduction:

Intelligent meter is a kind of programmable electric digital meter, It can measure single phase and three-phase voltages and currents accurately .With four keys on the front panel,we can set the parameters. With RS485 communication interforce,Modbus protocol,Switch I/O module and relay alarm function,etc.With digital input or digital output,we can realize alarming or controlling other equipment (contactor) remotely.

Measurement: I/U/KW/KVar/KWh/KVarh/Hz,etc.
