ANALYZER MEASURES AND RECORDS ACCORDING TO THE IEC 61000-4-30 CLASS S STANDARD.
Features of Sonel PQM-700 Power Quality Analyzer
- power to the analyzer is supplied from tested mains (internal power supply) and is used in all types of networks from 64 V to 760 V, with particular emphasis on measurements at low voltage poles, due to the ease of connection,
- has an independent power supply socket, especially suited for voltage measurements for transformers and DC circuits,
- built-in real-time clock.
