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 number (address) of ammeter, active electrical energy initial reading, the password and so on

Reliable Design: It is a generation of products with keypad to input encrypted numbers, STS compliant.
Standard: IEC 62052-11, IEC 62053-21, IEC 62056-21
Anti-Tampering Detection: Terminal cover and top cover open detection.
Resistance on High frequency jamming circuit
Prevention of Missing Potential
Resistance on neutral disturbance
Using uni-directional counter system
