Digital Power Meter Model 66203/66204

Chroma 66203/66204 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 1P2W/1P3W/3P3W/3P4W/3V3A, as well as providing accurate standard power measurements common for most electrical devices. A unique feature of the 66203/66204 is its state-of-the-art DSP digitizing technology instead of less accurate and slower traditional analog circuits. The internal 16 bits analog/ digital converters with sampling rates of up to 250kHz provide both high speed and high accuracy measurements which is unprecedented within the industry for this class of power meters.

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 66203/66204 meters provide users with two standard versions for the remote interface (via rear panel connection) configured as USB with GPIB or USB with CAN.

The 66203/66204 are packaged in a 3U high, half rack enclosure suitable for bench top or system integration. The power meters are capable of supporting external shunts and CT for higher current applications. The 4-channel 66204 is suitable for input and output parameter measurement, and the efficiency of 3-phase PV inverters can be calculated with the measurement of the DC voltage/current at the input side of the inverter.

The 66203/66204 power meters include a 2-shunt design to provide highly accurate readings for both low and high current measurements. The power meters also support features such as Inrush current, Total Harmonic Distortion of V/I, and Energy measurements. With these practical functions, the 66203/66204 power meters are suitable for meeting the demanding tasks of R&D, production, and quality control departments.

The 66200 Power Meters provide graphical user interface software (Softpanels), which allows users to control and read measured parameters from a computer via a USB or GPIB interface. Users can easily observe measured voltage and current waveforms and monitor the changes in parameter readings by using the chat function. Additional features include a recording function that can record selected parameters and write data to a file for further analysis. The 66200 Softpanels support IEC 61000-3-2* harmonic current limit test (pre-compliance), allowing users to examine whether the UUT has met the harmonic current requirement. The Power Efficiency Softpanel* also integrates with Chroma’s electronic loads and AC Sources to provide an easy method of power efficiency testing and recording of data using the test report function, which automatically generates a report at the completion of testing
