Class A DIN 192x144 power quality analyzer for CTs or current clamps

PQM4000 is a high-end power quality analyzer, able to monitor and record the major power quality parameters. It provides an accurate measurement, voltage characteristics are monitored according to Class A specification. At the same time it acts as
event/fault recorder, capable to store a high number of voltage events and disturbances, frequency variations, inrush current, etc.
Additional PQ data can be recorded, such as Flicker, Unbalance, Harmonics and Interharmonics, Mains Signalling. It also provides standard power measurement data for three-phase systems. Extra voltage and current measurement channels give the possibility
to monitor Neutral Potential and Earth Leakage current.
PQM4000 is available in 2 models: one for external standard CTs with 1 or 5A output and another one for current clamps with 1 or 3V ouput. In this way maximum flexibility is granted even on existing plants.
