Digital Power Meters

Better Accuracy Across the Board

Chroma’s Digital Power Meters are designed for both single-phase and multiple phase measurements of AC power signals and related parameters common to most electronic products. Instead of traditional analog measurement circuits the 66200 Digital Power Meter uses state-of-the-art DSP digitizing technology. The internal 16 bits analog/digital converters with sampling rates of up to 250KHz provide both high speed and high accuracy measurements which is unprecedented within the industry for this class of power meters current on the market.

Webinar: How to Achieve Accurate Power Measurements Testing AC Power Signals

This seminar covers the use of power meters, standards, and measurement parameters including Vrms, Vpeak+, Vpeak-, V_harmonic, V_THD, CFV (Crest Factor Voltage), Irms, Ipeak+, Ipeak-, I_harmonic, I_THD, Is (Inrush Current), CFI (Crest Factor Current), W, VA, VAR, PF, Freq_V, Freq_I, Wh, Ah, and º (phase degree) when testing power conversion devices.

Our Digital Power Meters are designed to satisfy both automated test system and laboratory benchtop requirements.

Advantages include:

  • Highest accuracy available
  • Complies with IEC 62301/Energy Star power measurement frequency bandwidth > 3kHz (Filter ON) requirement
  • Cycle based measurement, 1.5sec smoothing filter, grouping settings are preferable for harmonics measurement requirement in according to IEC 61000-4-7
  • Harmonic and total harmonics distortion functions are standard, not extra cost options
  • More standard interface features
