Four-Wire Three-Phase Kilowatt Hour Meter with RTU Protocol - Prepayment Electricity Meter

The DTS368-D is a DIN-rail mounted meter designed for three-phase, three-wire or four-wire systems, capable of measuring both active and reactive energy consumption. This modern smart energy meter, available in a 7-modular configuration, incorporates advanced technology to ensure high quality, stability, and excellent electromagnetic interference resistance. It also features low power consumption and adheres to international standards. Key advantages include its compact size, lightweight design, high precision, and suitability for applications such as office buildings, shopping malls, airports, and distribution boxes.
