Why Choose the Lovato DMED302 Three-Phase Energy Meter?
The Lovato DMED302 is a versatile three-phase digital energy meter and multi-measurement instrument designed for accurate monitoring of electrical energy consumption and generation in industrial, commercial and building energy-management applications. As part of the Lovato DME energy meter series, it combines direct current measurement, a backlit LCD display and integrated M-Bus communication in a compact DIN rail enclosure.
Designed for three-phase systems with neutral, the DMED302 supports direct connection up to 80 A, eliminating the need for external current transformers in suitable circuits. It measures imported and exported active energy as well as imported and exported reactive energy, while additional electrical measurements can be viewed locally on the backlit display.
The DMED302 operates with rated measuring voltages of 380–415 V AC phase-to-phase and 220–240 V AC phase-to-neutral. Its integrated M-Bus interface enables connection to compatible remote metering and energy-management systems, while the standard 4U, 72 mm wide DIN rail housing provides straightforward installation in electrical distribution boards and control panels.
