Why Choose the Lovato DMK70R1 Three-Phase Digital Voltmeter?
The Lovato DMK70R1 is a compact three-phase digital voltmeter designed for continuous voltage monitoring, alarm signalling and protection in industrial switchboards, distribution boards and machinery control systems. It displays the voltage measured across each phase and between phases, providing operators with a clear overview of the condition of a three-phase electrical supply.
The instrument uses True RMS measurement to provide accurate and stable readings, including where voltage waveforms contain harmonics or distortion. 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 DMK70R1 stores minimum and maximum values for all monitored voltages and includes a programmable relay output with control and protection functions. Its compact three-module format allows straightforward installation on a standard DIN rail, making it ideal for new panel builds, system upgrades and electrical monitoring applications where panel space is limited.

Reliable Three-Phase Voltage Monitoring and Protection
Three-phase voltage monitoring helps engineers identify overvoltage, undervoltage, supply imbalance and phase-related faults before they cause damage or production downtime. By displaying both phase-to-neutral and phase-to-phase values, the Lovato DMK70R1 provides a detailed view of the electrical supply from one compact instrument.
The programmable relay output allows the meter to activate an alarm, switch a contactor or interface with an external control system when a configured voltage condition occurs. This makes the DMK70R1 suitable for automatic voltage supervision, supply protection and preventative maintenance applications.
