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 200KHz provide both high speed and high accuracy measurements which is unprecedented within the industry for this class of power meters current on the market.

Chroma 66203/66204 Digital Power Meters are designed for multiple phase power measurement applications. The wiring mode function allows the user to take accurate power measurements for various wiring modes as well as providing accurate standard power measurements common for most electrical devices.


Each channel of 66203/66204 has the ability to provide independent measurements; hence the meters are suitable for multi-point measurement applications such as PV inverter testing. Instruments are designed for measuring DC input parameters as well as three phase AC readings on the output side. The overall efficiency for the PV inverter can easily be obtained by built-in functions. In order to meet high voltage applications (up to 1200Vrms) Chroma offers an HV option kit.


With the wiring mode set as 1P2W, the 66204 Power Meter has the capability of performing up to 4 simultaneous power measurements. The meters are also designed to comply with power measurement requirements in accordance to many international standards such as Energy Star/EN 50564/IEC 62301/ ErP.
