Detailed Product Description

Product Brief Introduction

Single-phase Electronic Watt-hour Meter adopt exclusive use LSI , The device with few periphery component, simple structure, high reliability, low power consumption, long life etc, is suitable for the single-phase AC active electric energy with rated frequency of 50 HZ. The performance conform to the technical requirements for single-phase Electronic Watt-hour Meter stipulated in GB/T 17125-2002 Standard.

Function and Feature

1.Measure active electric energy, do not need calibrate after long-term operation

2. Long-service life, accessible 10 years

3. Sampling current at the same time between phase line and middle line, Use the larger as valid sampling, prevent one fire one ground wire from electricity stealing thoroughly

4.Adopting exclusive use LSI and SMT surface fixing technique, Having advance technics and simple structure

5.Adopting latest electricity dedication integrated circuit including digital multiplier overseas, Greatly improved dynamic working range of Meter

6. Have good mistake linearity in the range of 5%Ib~Imax

7.Adopting high reliability and long life electronic component, So the Meter assume feature of high reliability and long life

8. Low self-power consumption, strong overload
