Why Choose the Lovato DMED330 Three-phase CT Energy Meter?
The Lovato DMED330 is a professional three-phase digital energy meter designed for accurate monitoring of electrical systems using 1 A or 5 A secondary current transformers. As part of the Lovato DME energy meter range, it combines comprehensive multi-measurement functionality with an integrated RS485 Modbus RTU/ASCII communication interface in a compact DIN rail mounted unit.
Suitable for three-phase systems with or without a neutral conductor, the DMED330 measures imported and exported active energy, reactive energy, voltage, current, power, power factor and frequency. It also supports monitoring of three independent single-phase loads, providing separate energy and hour counters for each phase.
With its compact 4-module DIN rail housing, backlit LCD display and isolated RS485 interface, the DMED330 is an excellent solution for industrial switchboards, commercial buildings, OEM machinery and building management systems requiring dependable remote energy monitoring.
