Application of Acrel ADF400L Multi Circuits Energy Meter in Vietnam
Abstract:Thisarticle introduces the application of ADF400L Multi Circuits Energy Meter inVietnam. ADF400L series multi-channel energy meter, through the way ofcombination module can realize less than 36 circuits single-phase or 12circuits three-phase, CT connect or direct connect. this series of energy meterwith high accuracy, high concentration, centralized management,installation flexibility, the advantages of each other noninterference by thecommunity, schools, enterprises of all areas. The series of meters supportprepaid power function.
