Application
DDS5558 LTwo-Phase watt-hour meter is utilized digital sampling technology and advanced SMT technology The meter has unbeatable accuracy and high reliability. It is designed and manufactured according to actual situations of resident usage of electricity. The two-phase voltage and current through the sampling circuit switched into signals and the signals into a two-phase energy
measurement specific integrated chip. The specific IC put out pulse signals which are proportional to the measured two-phase power to drive the register, to achieve measuring two-phase energy. At the same time, the energy meter output power test pulse with isolated optical coupler.
Features
1. Bidirectional measurement
2. Indication: Pulse, reverse current, phase failure
