DMED111 Lovato 1OUT 1PH 40A PROGRAMMABLEDIGITAL METER RS485

Why Choose the Lovato DMED111 Single-Phase Energy Meter?

The Lovato DMED111 is a compact digital single-phase energy meter and electrical measuring instrument designed for accurate monitoring of energy consumption and electrical parameters in industrial, commercial and building installations. As part of the Lovato DME energy meter series, it combines direct current measurement up to 40 A, an LCD display and integrated RS485 communication within a space-saving single-module enclosure.

Designed for multifunction energy monitoring, the DMED111 measures imported active and reactive energy together with key electrical parameters including voltage, current, active power, reactive power, power factor and frequency. Total and resettable partial energy counters are available, along with total and partial hour counters and demand measurements, allowing the meter to provide considerably more information than a basic kWh meter.

With direct connection for loads up to 40 A and rated phase-to-neutral voltages of 110–120 / 220–240 V AC, the DMED111 is suitable for a wide range of single-phase electrical systems. Its integrated RS485 interface supporting Modbus RTU and ASCII protocols enables measured data to be incorporated into compatible energy management, monitoring and supervisory systems.

Key Advantages

• Compact single-phase digital energy meter for electrical monitoring applications.

Accurate Energy Monitoring with RS485 Communication

Digital energy meters such as the Lovato DMED111 provide detailed information about electrical consumption and operating conditions. In addition to recording active and reactive energy, the meter can display voltage, current, active power, reactive power, power factor, frequency and demand information, helping users analyse energy usage and identify changes in electrical loads.

The integrated RS485 interface allows the DMED111 to communicate with compatible supervisory and energy-management systems using Modbus RTU or ASCII protocols. This makes the meter particularly suitable for installations where electrical measurements need to be collected remotely, logged or incorporated into a wider monitoring system.

Typical Applications

• Single-phase industrial energy monitoring.
• Commercial building energy measurement.
• Electrical distribution and control panels.
• Machine and equipment energy monitoring.
• Energy management and consumption analysis systems.
• Remote metering using RS485 networks.
• Building automation and supervisory monitoring systems.
