DMG900D048 – MULTIMETRO DIGITALE DA INCASSO 96X96
Lovato DMG900D048 expandable flush-mounted digital power analyser with 12, 24 or 48 V DC auxiliary supply, 128 × 112 pixel touch-screen LCD, True RMS measurement and harmonic analysis up to the 63rd order.
Why Choose the Lovato DMG900D048 Digital Power Analyser?
The Lovato DMG900D048 is an advanced flush-mounted multifunction digital power analyser designed for detailed monitoring of single-phase and three-phase electrical networks. Its high-resolution 128 × 112 pixel graphic touch-screen LCD, precise True RMS measurement and comprehensive power-quality functions make it suitable for demanding industrial, commercial and infrastructure applications.
The DMG900D048 measures voltage, current, active power, reactive power, apparent power, frequency, power factor, electrical energy and harmonic distortion. Individual voltage and current harmonic analysis up to the 63rd harmonic order helps engineers identify waveform distortion, neutral loading and power-quality issues caused by variable speed drives, UPS equipment and other non-linear loads.
This version operates from a nominal 12, 24 or 48 V DC auxiliary supply, making it particularly suitable for battery-backed control panels, substations, renewable energy systems and industrial automation installations. The analyser supports external 1 A or 5 A current transformers and can be expanded using compatible Lovato EXP modules. The DMG900D048 is listed as out of catalogue, so contact LED Controls to discuss remaining availability or a suitable replacement.

Advanced Power Analysis for DC Supplied Systems
The Lovato DMG900D048 provides comprehensive electrical-network analysis for installations where the monitoring instrument must operate from a low-voltage DC control supply. Its True RMS technology delivers dependable measurements in networks containing distorted waveforms, while the fourth current input allows neutral-current monitoring in three-phase four-wire systems.
Detailed harmonic analysis and event monitoring help engineers investigate overheating, nuisance tripping, excessive neutral current and reduced equipment efficiency. Optional EXP modules can add RS485, Ethernet, digital inputs, relay outputs and other functions for integration with PLCs, SCADA platforms and energy-management systems.
