Why Choose the Lovato DMK80R1 Single-Phase Digital Voltmeter?
The Lovato DMK80R1 is a compact single-phase digital voltmeter designed for continuous AC voltage monitoring, alarm signalling and protection in industrial switchboards, distribution boards and machinery control systems. It displays the present voltage together with stored minimum and maximum values, helping operators identify supply variations and abnormal electrical conditions.
The instrument uses True RMS measurement to provide dependable readings, including where voltage waveforms are affected by harmonics or distortion from variable speed drives, electronic power supplies and other non-linear equipment. Its wide measuring range of 15 to 660 V AC makes it suitable for many low-voltage monitoring applications.
The DMK80R1 also includes a programmable relay output with control and protection functions. This allows the meter to activate an alarm, switch a contactor or interface with an external control circuit when configured voltage thresholds are reached. Its compact three-module DIN rail housing simplifies installation in electrical panels where available space is limited.
