▷Product Overview
This three-phase electronic type active watt-hour meter adopts advanced microelectronics technique and SMT manufacturing technology. Its performance
conforms to IEC 62053-21 standard. The 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 RS485 interface communicating etc,with
characteristics of LCD displaying means、HHU for setting power consumption
data and reading serial number,so this product is ideal measuring device for
inhabitant power uti l ization charging ,Besides ,it also owns many advantages as
high metering precision、high sensitivity、rel iable performance、wide load、low
power consumption、smal l volume、l ight weight、simply operating and easy for
instal lation etc.

▷Features
● Owning forward and reverse direction metering function, besides, it can
accumulate electric quantity in one same direction ,that is, calculating reverse
energy electro into forward direction.
●The nic meter adopts seven-digit displaying, of which there are five integer-
place and two decimal-place; whi le also can be six integer-place and one
decimal-place; The unit is ki lowatt-hour, making record of accumulated total
electric power consumption.
● The 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.
●Own passive isolated type electric energy impulse output terminal, the impulse
output is square wave, and the impulse width is not smal ler than 80ms±20%.
● 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.
