PQM-711 Power Quality Analyzer
Model: PQM-711
Brand: Sonel
Class A remote analysis
The Sonel PQM-711 versatile power quality analyser for remote analysis in the A class is a device suitable for use on all types of networks with a rated voltage range from 110 V to 1000 V either directly or indirectly through transformers.
Based on advanced technology, the Sonel PQM-711 power quality analyser allows comprehensive measurement, analysis and recording of 50/60 Hz power network parameters and power quality according to the European standard EN 50160.
Features
- Remote control and data transfer through a built-in GSM modem.
- Anti-theft feature – SMS notification in the event of position change (built-in GPS receiver).
- Real-time clock synchronized to GPS protocol.
- Remote control of the analyzer via software: Sonel Analysis (Wi-Fi and GSM for Windows) or Sonel Analysis Mobile (Wi-Fi for Android).
