Power Quality Analyzer – Overview

This Power Quality Analyzer allows for versatile measurement, analysis, and registration of energy network parameters DC and 50/60Hz. This includes measuring the quality of electric energy in accordance with the European standard EN 50160. To Guarantee accuracy, all parameters are measured with Class S according to the IEC 61000-4-30 STANDARD.

This is the largest in this class of power quality analyzers and has a 7-inch colour touch screen which enables intuitive and ergonomic operation. Thanks to the built-in lithium-ion battery, the analyzer allows for work during the measurement without the necessity of connecting an external AC adapter.

The analyzer can be used directly, or indirectly via transformers in virtually all kinds of networks with rated voltage from 54V to 760V. Due to its mobility and autonomy, any problems occurring in the supply networks can be diagnosed on the spot. With a safety rating of CAT IV 600V, the Power quality analyzer provides peace of mind during everyday use. The PQM-707 can therefore be used in the field of professional power engineering, maintenance services in industrial plants, as well as network analysis.
