Main functions
- Active energy measuring, without calibration during long operating period;
- Adopting special large scale integrated circuit and SMT technology, with advanced process and simple construction;
- Adopting newest special integrated circuit for energy measurement with digital multiplier inside, as a result that dynamic working scope of meter is raised remarkably;
- Excellent error linearity within 1% Ib~Imax;
- Long service life and high reliability due to high-quality components adopted;
- Wide operating temperature range : -40oC ~ +70oC;
- RS485 port;
- Anti Tamper fraud design: to prevent one-fire-one-grounding tamper fraud by using the bigger current-sampling value among phase line current sampling and neutral line current sampling;
