Chroma Intros Multiple Phase Power Meters
Digital power meter.
Foothill Ranch, CA — Chroma Systems Solutions, Inc. has expanded its 66200 series of high speed, high accuracy Digital Power Meters. Newly added are three- and four-channel power meters designed for multiple phase power measurement applications. The meters are designed to comply with power measurement requirements in accordance with international standards such as Energy Star®, EN 50564, IEC 62301 and ErP.

The new model 66203 and 66204 Power Meters allow users to take accurate power measurements for various wiring modes including three phase WYE and DELTA and split phase. These power meters incorporate state-of-the-art DSP digitizing technology which replaces less accurate and slower traditional analog circuits. The internal 16-bit analog/digital converters with sampling rates of up to 250kHz provide both high speed and high accuracy measurements.

The 66203 and 66204 are packaged in a 3U high, half rack enclosure suitable for bench top or system integration. The 4-channel 66204 is suitable for functional and efficiency measurements of 3-phase grid inverters as the fourth channel may be used to measure the DC voltage, current, and power on the input side of the inverter. The 66203 and 66204 power meters include a 2-shunt design to provide highly accurate readings for both low and high current measurements and are capable of supporting external shunts and current transformers for higher current applications. The power meters also support inrush current, total harmonic distortion of V/I, and energy measurements. These practical functions make the new power meters suitable for the demanding tasks of R&D, production and quality control departments.

The instruments include a four part display with 7-segment LED front panel readouts. Users can easily select desired parameters and readouts with a touch of a button. The 66203 and 66204 meters also include remote control using USB or GPIB interfaces using rear panel connections. Optional software for increased operational efficiency and reporting is also available.
