Why Choose the Lovato DMK10R1 Three-Phase Digital Voltmeter?
The Lovato DMK10R1 is a compact and accurate three-phase digital voltmeter designed for continuous voltage monitoring, control and protection in industrial switchboards, machinery panels and electrical distribution systems. It displays individual phase-to-neutral and phase-to-phase voltage values, allowing engineers to assess the condition of a three-phase supply from a single panel-mounted instrument.
The meter uses True RMS measurement to provide reliable readings, including where electrical waveforms are affected by variable speed drives, switched-mode power supplies or other non-linear loads. It measures phase-to-phase voltages from 15 to 660 V AC and phase-to-neutral voltages from 10 to 382 V AC, making it suitable for a broad range of low-voltage installations.
The DMK10R1 also records the minimum and maximum voltage measured on each phase and between phases. An integrated programmable relay output can operate an external alarm, contactor or control circuit when configured voltage conditions occur. Its compact 96 × 48 mm flush-mounted format makes it ideal for professional panel-building and system-monitoring applications.

Reliable Three-Phase Voltage Monitoring and Protection
Three-phase voltage monitoring helps engineers identify supply imbalance, phase loss, overvoltage and undervoltage conditions before they cause equipment failure or production disruption. By displaying both phase-to-neutral and phase-to-phase measurements, the Lovato DMK10R1 provides a detailed overview of the electrical supply from one compact instrument.
The programmable relay output extends the meter beyond basic indication. It can activate an external warning device, switch a contactor or interface with a control system when measured voltage reaches configured limits, making the DMK10R1 suitable for automated voltage supervision and protective control applications.
Typical Applications
- Industrial switchboards and electrical distribution panels.
- Three-phase machinery and process control cabinets.
- Overvoltage and undervoltage monitoring.
- Phase imbalance and phase-loss supervision.
