1. General：

The ADF400L series multi-user energy meter can achieve up to 12 three-phase or 36 single-phase direct access measurements through a combination of modules, or 12 three-phase inductor access measurements, or a combination of direct access and transformer access. This series of electric energy meters is preferred by communities, schools, companies, etc. Due to its high precision, centralized installation, centralized management, high installation flexibility and non-interference. This series of meters supports prepaid functions.
