Single-phase two wire electronic watt-hour meter

Detailed Product Description

Function and Feature

1. Measure active electric energy, Do not need calibrate for

long-term operation
2. Adopt dedication meterage chip ADE7755
3. Adopting latest electricity dedication integrated circuit

including digital multiplier overseas, Greatly improved dynamic

working range of Meter , Making 10 multiple actual overload
4. Have good mistake linearity in the range of 5%Ib~Imax
5. Few periphery component, simple structure,low power

consumption
6. Adopting high reliability and long life electronic

component, So the Meter assume feature of high reliability and

long life
