Lovato DMED300T2 Three-Phase Energy Meter

Name: Lovato DMED300T2 Three-Phase Energy Meter – Manual & Quote
Brand: Lovato Electric
SKU: DMED300T2

Direct-connection three-phase energy metering on DIN rail

The DMED300T2 is a three-phase energy meter with neutral from the Lovato Electric DME range. It connects directly to the circuit up to 80 A, so no current transformers are needed, and it measures imported and exported active and reactive energy. It occupies four DIN-rail modules and suits sub-metering of feeders, tenant loads, pumps and machine lines. Typical applications include feeder sub-metering, tenant cost allocation and energy reporting in distribution boards, where a compact meter with pulse outputs is easier to integrate than a full network analyzer.

The meter shows multiple measurements on its LCD and offers two programmable static pulse outputs for remote counting by a PLC or energy management system. It is non-expandable and has no built-in communication port, which keeps installation simple: wire the three phases and neutral, set the pulse rate if needed and read energy on the display. The values below come from the Lovato data sheet.

Pulse outputs and typical use

Each static output can be programmed to 1, 10, 100 or 1000 pulses per kWh, with a 100 ms pulse for the lower rates and 60 ms for 1000 pulses. This lets a PLC counter input or a pulse-based energy gateway collect consumption without a serial link. Because the meter is not MID certified, it is intended for internal sub-metering and cost allocation rather than legal billing.

Choosing the right DME meter

The DME family also includes CT-connected and communicating models, so please check the order code with us if you need Modbus, current transformer inputs or harmonic analysis, which the DMED300T2 does not provide. Lovato lists the DMXP04 panel-mounting accessory for four-module devices. For other power monitoring on the site, see the Janitza UMG 508, or browse automation accessories.
