Lovato DMG2000: modular network analyser for electrical panels
The Lovato DMG2000 network analyser multimeter is a multifunction digital instrument designed for measuring and supervising the main electrical parameters in industrial, tertiary, and building automation installations. Thanks to its modular format on a 35 mm DIN rail, it easily integrates into electrical panels, simplifying the adoption of an energy monitoring system without overhauling the existing wiring. The colour display enhances the user experience: it allows for clear visualization of voltages, currents, powers, and energies, facilitating quick checks during testing, maintenance, and diagnostics.
Reliable energy measurements: class 0.5s for active energy
When the goal is to account for or analyse consumption, accuracy matters. DMG2000 offers an active energy measurement accuracy of Class 0.5s according to IEC/EN 62053-22, a specification suitable for many monitoring and internal consumption allocation applications. For reactive energy, the classification is Class 2 according to IEC/EN 62053-23, useful for evaluating power factor correction and inefficiencies related to inductive loads, optimizing costs and performance of the installation.
Harmonic analysis up to the 63rd order: energy quality under control
With the increase of inverters, UPS, switching power supplies, and LED lighting, the presence of harmonics is increasingly common. The DMG2000 integrates harmonic analysis up to the 63rd order, a fundamental tool for identifying distortions and criticalities that can cause overheating, untimely tripping, or reduced component lifespan. Having this data directly at the panel, with a colour display, helps to intervene more precisely on filters, power factor correction, and load balancing.
Integrated Ethernet: ready for supervision and integration
The presence of the integrated Ethernet port makes the DMG2000 particularly convenient in contexts where centralized data collection is required. By connecting it to the LAN network, you can integrate the instrument into supervision, energy monitoring, or predictive maintenance systems, improving visibility on consumption and electrical parameters. Being non-expandable, the DMG2000 is a compact and complete solution designed for those who want a ready-to-use device without additional modules.
Installation and compatibility with CT: simple in new installations and retrofits
The DMG2000 measures current through current transformers (CT) with secondary /5A or /1A, a compatibility that facilitates installation in new installations and replacement/upgrades in existing panels. The auxiliary power supply 100240 VAC further simplifies integration, adapting to the main panel power supplies.
