  • Equipment monitoring to determine and/or maintain efficiency.
  • Process monitoring and/or controlling to maintain consistent product quality.
  • For use with SCR controlled, chopped, or otherwise distorted waveforms.
  • 0.25% Accuracy.
  • True Power measurements for sinusoidal and distorted waveforms.
  • Volt-Ampere measurement for sinusoidal and distorted waveforms.
  • Power Factor is derived from the ratio of True Power to Apparent Power and remains accurate for SCR controlled or otherwise distorted waveforms.
  • Three separate output signals – one each for Watts, Power Factor, Volt-Amperes.
  • Wide frequency range – 50 to 400Hz.
