点击次数:233发布时间:2021-12-15

Abstract:This article introduces the application of ADF400L Multi Circuits Energy Meter in Vietnam. ADF400L series multi-channel energy meter, through the way of combination module can realize largest 36 circuits single-phase or 12 circuits three-phase, CT connect or direct connect. this series of energy meter with high accuracy, high concentration, centralized management, installation flexibility, the advantages of each other noninterference by the community, schools, enterprises of all areas. The series of meters support prepaid power function.

 

 

1.Project Overview

The company is located in Vietnam.The customers need 2 channels three-phase direct access and 2 channels three-phase secondary access measurement. Acrel ADF400L series energy meters meet the user's application and conditions.

 

2.Product Specification
