The ZES Zimmer LMG600 - series power analyzers—most notably the LMG671 - are high - precision instruments designed for measuring voltage, current, power, efficiency, harmonics, and dynamic behavior in modern electrical and power - electronic systems. They combine very wide measurement ranges, from microamp - level currents to tens of amperes and from millivolt - level signals up to high voltages, with broad bandwidths that extend into the megahertz range. This allows them to capture both slow, fundamental power signals and fast - changing switching phenomena produced by converters, inverters, motor drives, and other high - frequency equipment. A key characteristic of the series is its DualPath architecture, which records narrowband (fundamental) and broadband (full - spectrum) signals simultaneously, ensuring accurate results even in complex switching environments where conventional analyzers struggle with aliasing or filtering trade - offs.
The LMG analyzers support multiple synchronized measurement channels—up to seven in the case of the LMG671 - which makes them suitable for three - phase systems, multi - input/multi - output converters, EV drivetrains, transformer testing setups, and general laboratory energy - flow analysis. They accept direct inputs or external sensors through plug - in modules, enabling flexibility across low - power electronics, industrial drives, and high - power test benches. Their measurement precision reaches reference - grade levels, with very low error margins that remain stable across wide dynamic ranges.
Beyond raw measurement capability, the instruments provide extensive analytical functions such as harmonic and interharmonic analysis to high orders, power - quality evaluation, efficiency and loss calculations, and long - term data logging. They integrate easily into automated test systems through interfaces like USB, LAN, RS - 232, and CAN, and they support scripting and advanced data export for laboratory automation. Altogether, the LMG671 and related models serve as comprehensive, laboratory - class power analyzers suited for R&D, industrial validation, compliance testing, and any application that requires high - accuracy, high - bandwidth electrical power measurement.
