Digital Display Two Phase Three Wire Electronic Energy Meter For Energy Monitoring
Product Description
Our Two-Phase watt-hour meter is utlized digital sampling technolpgy and advanced SMT technology The meter has unbeatable accuracy and high reliability. It is designed and manufactured according to acutual situations of resident usage of electricity. The two-phase voltage and current through the sampling circuit switched into signals ans the signals into a two-phase energy measurement specific intergreted chip. The specific IC put out pulse signals which are preportional to the measured two-phase power to drive the register, to achive measuring two-phase energy. At the same time, the energy meter output power tesr pulse with isoltaed optical coupler.
