The LMG95 single-phase precision power meter is an outstanding product in the proven LMG series of ZES ZIMMER precision power measuring devices. Highly accurate continuously gapless signal measurement and processing, ergonomic operation and presentation of the results, interfaces with high data rates for effi cient system applications – these are the performance features which distinguish the LMG95.
The high precision power measurements on components and devices that are required in development, quality assurance and manufacturing can be performed with ease, independent of whether the current and voltage are sinusoidal or distorted, whether the load is linear or not, or whether the circuit works in a chopped, pulsed or another modulation mode. The extended possibilities of synchronization on the periodicity of the measured signal always produce distinct and stable measurement displays and results.
Isolated measurement inputs with direct measurement ranges up to 600V (1600Vpeak) and 20A (960Apeak for the measurement of inrush currents) and the input for current measurements using a shunt or other transducer measure the incoming measurement signals exactly and without any aberrations.
With a basic accuracy of 0.025% is this the most precise instrument in its class and therefore it is used as a reference device for energy meters, power meters, power measurement transformers and trms meters for current and voltage.
The harmonic analysis in full compliance with the EN61000-3-2/-12 standard is already available in the basic unit. The fl icker meter in compliance with EN61000-4-15 for the measurement of fl icker ( voltage variations) and with EN61000-3-3/-11 is available as an option. These two functions also considerably extend the possible applications of the LMG95 in R&D laboratories. If suitable stable voltage sources are available, tests for CE compliance can be performed in accordance with EN61000-3-2/-3/-11/-12.
The LMG95 is used as an analyzer in CE test systems to test electrical devices on harmonics and fl icker and their effect on mains. The ZES ZIMMER test system CE-Test61k is usually equipped with a precision power meter LMG500 for 3-phase application or with a LMG95 for singlephase applications. Components can also be ordered and used separately, easy integration of customer owned power sources.
All ZES ZIMMER power meters of the LMG series, the current sensors of PCT series and the voltage sensors of the HST series are carefully tested, adjusted and calibrated prior to shipment and are subject to strict quality controls.
ZES ZIMMER guarantees for a period of 24 months from first delivery that these products are free from defects in material or workmanship.
