DMG800 – FLUSH METER 96X96 100-440VAC/110-250VDC
Lovato DMG800 expandable flush-mounted multifunction digital multimeter with a 128 × 80 pixel graphic LCD, True RMS measurement, 31st-order harmonic analysis and support for 1 A or 5 A current transformers.
Why Choose the Lovato DMG800 Digital Multimeter?
The Lovato DMG800 is an expandable flush-mounted multifunction digital multimeter and electrical network analyser designed for detailed monitoring of single-phase and three-phase power systems. Its high-resolution graphic display, accurate True RMS measurement and advanced harmonic analysis make it suitable for industrial switchboards, energy-management systems and power-quality monitoring applications.
The DMG800 measures voltage, current, active power, reactive power, apparent power, frequency, power factor and electrical energy. It also provides individual harmonic analysis up to the 31st harmonic order, helping engineers identify waveform distortion caused by variable speed drives, power supplies and other non-linear electrical loads.
Designed for external 1 A or 5 A current transformers, the meter provides Class 0.5S active energy measurement accuracy and can be expanded with compatible Lovato EXP modules. Please note that the Lovato DMG800 is listed as out of catalogue. Contact LED Controls to check availability or identify a suitable current replacement.
