INTRODUCTION
The three-phase energy meter with CT insertion, model DME D305T2MID, has been designed to combine the utmost ease of use with a wide range of advanced functions. Despite the extremely limited dimensions of
the modular housing (just 4 modules), the energy meter features the same performance as a high-level device. The backlit LCD display permits a clear and intuitive user interface. The DME D305T2MID also features
2 static outputs for pulse generation and a tariff input.
