ANALYZER MEASURES AND RECORDS ACCORDING TO THE IEC 61000-4-30 CLASS A STANDARD

  • 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.
  • Remote control and data transfer through a built-in GSM modem (GPRS).
  • Anti-theft feature - SMS notification in the event of position change - built-in GPS receiver.
  • Real-time clock synchronized to GPS protocol.
