£260.12
The Lovato DMK75R1 is a compact three-phase digital voltmeter, ammeter and wattmeter designed for comprehensive electrical monitoring in industrial switchboards, machinery panels and power distribution systems. Housed in a space-saving 3-module DIN rail enclosure, it combines multiple electrical measurements within a single instrument, reducing panel space requirements while simplifying installation.
Using True RMS measurement, the DMK75R1 provides dependable readings even where electrical waveforms contain harmonic distortion generated by variable speed drives, UPS systems or other non-linear loads. It measures phase and line voltages, phase currents and active power for each phase together with total three-phase power, making it ideal for monitoring electrical system performance.
The instrument also stores minimum and maximum measured values and incorporates a programmable relay output for alarm, control and protection functions. Its DIN rail mounting format makes it suitable for new electrical installations as well as retrofit monitoring applications where enclosure space is at a premium.
The Lovato DMK75R1 enables engineers to monitor voltage, current and active power from a single DIN rail instrument, simplifying fault diagnosis and routine electrical supervision. Displaying both individual phase values and total active power provides valuable information for identifying load imbalance, excessive demand and abnormal operating conditions.
Its programmable relay output enables automatic alarm signalling or control actions when user-defined thresholds are exceeded, making the DMK75R1 suitable for preventative maintenance, machinery protection and energy monitoring applications.
