Why Choose the Lovato DMK00R1 Single-Phase Digital Voltmeter?
The Lovato DMK00R1 is a compact single-phase digital voltmeter designed for accurate AC voltage monitoring, control and protection within industrial switchboards, machinery panels and electrical distribution systems. It combines clear digital indication with programmable relay functionality, allowing the instrument to monitor voltage conditions and operate external control or alarm circuits.
The meter measures voltage using the True RMS method, helping maintain dependable accuracy when electrical waveforms are distorted by variable speed drives, switched-mode power supplies or other non-linear loads. Its broad direct operating range of 15 to 660 V AC makes it suitable for many low-voltage applications, while programmable voltage transformer scaling supports indirect measurement on higher-voltage systems.
Unlike the standard DMK00, the DMK00R1 includes a programmable relay output for control and protection functions. This enables the meter to signal abnormal voltage conditions or control connected equipment according to configured thresholds. Its 96 × 48 mm flush-mounted housing, removable terminals and IP54 front protection make it well suited to professional panel-building applications.

Voltage Monitoring with Programmable Relay Control
Digital panel voltmeters provide continuous indication of the electrical supply, helping operators identify abnormal voltage levels, supply instability and developing installation faults. The DMK00R1 also stores minimum and maximum readings, allowing maintenance personnel to review voltage variations that may occur between inspections.
Its programmable relay output extends the instrument beyond basic indication. The relay can be configured to operate external alarms, contactors or control circuits when monitored voltage reaches defined conditions, making the DMK00R1 suitable for undervoltage, overvoltage and general voltage supervision applications.
