Product Overview

CHROMA 66203

The Chroma 66203 Power Meter is 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 66203 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.

The wiring mode function of the 66203 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 the 66203 has the ability to provide independent measurements; therefore the meter is 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.
