Chroma 66203/66204 Power Meters are designed for mul t ipl e pha s e powe r me a surement applications. The wiring mode function allows the user to take accurate power measurements for various wiring modes (see figure below) 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 as shown. 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.
User could implement 3P3W (Three Phase Three Wire) wiring mode for three phase power measurement application. Such as AC motor inverter testing.
66203/66204 Power Meters suppor t external shunt function for high current (>20A) measurement application.
