Why Choose the Lovato DMK15R1 Three-Phase Digital Multimeter?
The Lovato DMK15R1 is a multifunction three-phase digital voltmeter, ammeter and wattmeter designed for comprehensive electrical monitoring in industrial switchboards, machinery panels and power distribution systems. It combines voltage, current, frequency and active power measurement within one compact panel-mounted instrument, reducing the need for multiple separate meters.
The instrument uses True RMS measurement for both voltage and current, helping provide dependable readings where electrical waveforms contain harmonics or distortion. It displays three phase-to-neutral voltages, three phase-to-phase voltages, three phase-current values and four active power values covering each phase and the three-phase total.
The DMK15R1 also stores minimum and maximum measured values and includes a programmable relay output for control and protection functions. Its compact 96 × 48 mm flush-mounted format, removable terminals and IP54 front protection make it a practical choice for panel builders, electrical engineers and industrial maintenance teams.

Comprehensive Three-Phase Electrical Monitoring
Monitoring voltage, current and active power from a single instrument gives engineers a detailed view of electrical system performance. The Lovato DMK15R1 allows phase values to be compared individually, helping identify phase imbalance, abnormal loading, voltage variation and excessive power demand.
The programmable relay output enables the meter to operate an external alarm, contactor or control circuit when a configured electrical condition occurs. This makes it suitable for automated supervision, load control, overcurrent warning and general electrical protection applications.
