Why Choose the Lovato DMED330MID Three-phase MID Energy Meter?
The Lovato DMED330MID is a professional three-phase digital energy meter designed for accurate monitoring through external current transformers in commercial, industrial and building-services installations. Part of the Lovato DME energy meter range, it combines MID-certified energy measurement with comprehensive electrical monitoring and integrated RS485 communication.
Designed for connection to current transformers with a 5 A secondary output, the DMED330MID is suitable for higher-current circuits where direct-connected energy meters are not appropriate. It can be used on three-phase systems with or without neutral and provides detailed measurement of energy consumption, voltage, current, power, power factor and frequency.
The integrated RS485 Modbus communication interface allows measured data to be transferred to compatible PLCs, SCADA platforms, building management systems and energy-monitoring software. Its MID approval, clear backlit LCD display and compact 4-module DIN rail housing make it an effective solution for billing, cost allocation and remote energy management.

MID-certified Monitoring with RS485 Communication
The Lovato DMED330MID is designed for installations where external current transformers are required to measure higher electrical loads. The meter receives a standard 5 A secondary signal and calculates energy consumption according to the configured current-transformer ratio.
MID certification makes the meter suitable for qualifying billing and cost-allocation applications, while its integrated RS485 interface allows measurement data to be collected remotely. This provides facilities managers and engineers with centralised access to energy and electrical values for reporting, analysis and efficiency improvements.
Typical Applications
- Commercial tenant billing and cost allocation.
- Industrial switchboards and distribution panels.
- High-current circuits monitored through current transformers.
- Building management and SCADA systems.
- Factory and production energy monitoring.
- Commercial and industrial sub-metering.
- Remote Modbus energy-monitoring installations.
