Product Description
Single-phase three-wire LCD electrical smart meter with communication RS485
RS485 or the infrared programming
Function and features
1. Owning forward and reverse direction metering function, besides, it can accumulate
Electric quantity in one same direction, that is, calculation reverse electric quantity into
Forward direction.
2. The electric quantity adopts displaying, of which there are five integer-places and two
Decimal-place while also can be six integer-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. The parameter programming (RS485 or the infrared programming, setup, reading meter) be able to setup the active electrical energy initial reading, the password and so on
