The 66205 is the 2nd generation of the 66200 series power meter designed specifically for single channel measurement. Its state of 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.

The Smart Range function is one of the most important new features added to the 66205 power meter. Smart Range allows the power integration mode to perform active power measurements with the measurement range in auto mode. Chroma’s proprietary design automatically selects the appropriate range, based on changes in sensed voltage and current, ensures the best accuracy when integrating the measurements over time.

The 66205 provides 10 selectable current measurement ranges from 5mA up to 30A. External sensor options A662017~A662020 are available to increase the current measurement range. Six selectable voltage ranges are available up to 600V.

External sensor option A662012 can be used to increase the voltage measurement range to 1.2kV. The 66205 provides a low range error up to 0.05% and is capable of meeting the measurement uncertainty requirement of IEC 62301/EN50564.

66205 power meter is designed to comply with IEC 61000-4-7. Continuous high-performance harmonic measurement, with 5Hz frequency resolution and a packet harmonic function, it can accurately measure sub-harmonics, inter-harmonics and harmonics.

For remote operation, the 66205 offers 4 types of communication interfaces including GPIB, USB, RS-232 and LAN (optional). Using the softpanel, it can create complete test reports and perform power quality as well as regulation tests. In addition, its STORE function records the measured values and saves them to a USB storage device. The Limit function can be used for production tests by performing GO/NG tests on the upper and lower limits of voltage, current and power parameters; additionally, it can be integrated into automated production when I/O port is used. The 66205 is a great fit for meeting the demanding tasks of R&D, production and quality control.

The 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.

Use the AC Source synthesis function to generate a voltage waveform consisting of 220V at fundamental frequency 50Hz and 3rd harmonics with 22V as amplitude and 30 degree as phase angle.

Selecting voltage signal as sync signal : When the voltage signal distortion will be less than current and more stable, thus voltage is selected as sync signal source.

Selecting current signal as sync signal : When the current signal distortion will be less than voltage. Thus current is selected as sync signal source.
