Description

Features

  • Display of the power factor cos φ
  • Linear or non linear scale available
  • Low consumption
  • Wide frequency range of operation
  • Stromanschluss über Durchführungswandler
  • Exchangeable scale
  • Protective cover for terminals (optional)

Application

The instrument operates on fast sampling method of input quantities (current and voltage) on all tree phases. From the input data microprocessor calculates the power factor. It can be chosen between direct measuring of the power factor (linear cosφ-sclae) and measuring of the phase angle (non linear cosφ scale).
