Single phase anti-fraud energy meter (DDSJ1088)

1. Function
1)Active energy metering, no calibration is required after long time working;
2)Sample the phase current and neutral current simultaneity, in order to prevent the tamper electricity from live wire and earth wire.
3)Utilize with advanced metering chip and SMT technology.
4)Have good error linearity in the range of 5%Ib~Imax.
5)Long life and high reliably.
6)Wide range of operation temperature: -40~+60 degree
