Product Description

Multi-circuits Prepaid Energy Meter ADF400L (1-phase&3-phase)

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.

Note: 1、this product is combined with main module , direct connect and CT connect module；
2、This product can be max 12 circuits 3 phase (36 circuits single phase)
