☆ Product Brief Introduction

   This three-phase electronic type active watt-hour 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、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 measuring device for inhabitant power utilization charging ,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 features  

 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.hen 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 Data programming(RS485 or infrared programming、setting and meter reading)also can set meter number  (Address)of  electric meter.Starting count of active electric energy and cipher etc.
