 Product brief introduction  

This Three-phase electronic active electronic instrument(smart meter,anolog meter)adopts advanced microelectronics technique and SMT manufacturing technology. Its performance conforms to GB/T17215-2002 standard. This three-phase electronic type active electric energy meter owns many functions as active forward direction and reverse electric quantity respectively metering or active forward reverse power accumulation metering infrared and RS-485 interface communicating etc,with characteristics of LCD displaying means hand meter reading device for setting power consumption data and reading electric quantity, so this product is ideal metering device for inhabitant power utilization ,Besides ,it also owns many advantages as high metering precision high sensitivity reliable performance wide load low power consumption small volume light weight simply operating and easy for installation etc.

Function and feature

1 Owning forward and reverse direction metering function, besides, it can accumulate electric quantity in one same direction that is, calculating reverse electric quantity into forward direction

2 The electric quantity adopts seven-digit displaying, of which there are five integer-places and two decimal-places; while also can be six integer-places and one decimal-place and one decimal-place; its unit is kilowatt-hour, making record of accumulated total electric power consumption.

3. When electric energy meter is communicated with external equipments, the communication indicator lamp would be brightened, which stands for that the electric energy meter stays at communication state

4 Own passive isolated type electric energy impulse output terminal, the impulse output is square wave, and the impulse width is not smaller than 80ms±20% .

5 Parameter programming (RS485 or infrared programming setting and meter reading) can set the number of electric meter starting count of active electric energy and cipher etc.
