Overview
The ADF400L series multi-user electric energy meter can achieve up to 12 three-phase or 36 single-phase direct
access measurement or 12 three-phase mutual inductor access measurement, a hybrid of direct access and mutual
inductor access through module combination measurement method. This series of electric energy meters are popular among communities, schools, enterprises, etc. due to their high accuracy, centralized installation, centralized management, high installation flexibility, and non-interference.
