The 66205 Digital Power Meter is the 2nd generation of the 66200 series designed specifically for single channel measurement. Its state-of-the-art design is capable of providing highly accurate power measurements to meet the requirements of IEC 62301/EN50564 standards. Functionality improvements of the 66205 increase power measurement capabilities to a wider range of applications.

Power Meter Measurement Parameters

66205 power meter is capable of providing the following reliable and accurate measurement parameters : 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, º (phase degree).

Parameter Measurement Method: a gapless continuous moving window average out the voltage and current parameter measurements within the time frame. Please note the time setting for the time frame is equivalent to data update rate x AVG number setting.

Line Filter Function

Line filter is a digital low pass filter with a high attenuation rate of ≥70dB. When line filter is enabled, the measured value will not include high frequency content, such as the high frequency noise of a switching converter. The 66205 offers three sets of line filter with cutoff frequency: OFF, 500 Hz and 5.5 kHz. The line filter with 5.5 kHz cutoff frequency is compliant to IEC 61000-3-2 international standards. It is suggested to turn this filter on when measuring harmonics.
