Penerangan
PQM4000 (DIN 192×144) 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. 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 (up to 63rd) and Interharmonics, Mains Signalling. Extra voltage and current measurement channels give the possibility to monitor Neutral Potential and Earth Leakage current.
PQM4000 is available for external standard CTs with 1 or 5A output or for current clamps.
PQM4000 includes different communication ports so the user can access it in different ways.
