66201 product overview
The 66201/66202 digital power meter is used to measure the power and other voltage and current parameters of single-phase AC power supplies, and is suitable for most electrical and electronic products. Different from the traditional way of using analog lines, 66201/66202 uses 16 bits of high resolution from analog to digital, a sampling frequency of up to 240kHz, and high-speed digital signal processing (DSP) technology. Compared with other brands of power meters of the same level, it can provide more functions, and faster measurement of stable and accurate values.
The 66201/66202 digital power meter series have four display windows, and provide different parameter reading at the same time. Users can easily select the value they want to read. The seven-segment display in each window provides a measurement resolution of 5 digits. In addition, there is a USB or GPIB interface on the back panel for users to choose and configure for digital control. In addition, the volume of the machine is 2U in height and half the width of a standard cabinet, which is suitable for system integration.

66201 Application Introduction
The 66200 series not only provides an average mode, but also provides a moving window method that allows users to set the length of time. All data in the window will be calculated during measurement, so no signal will be missed. In addition, it also provides INTEGRATION MODE to measure power, which meets the energy star test requirements.
Provides the function of measuring the total harmonic distortion of voltage and current (TOTAL HARMONIC DISTORTION), which can be directly displayed on the power meter. Some Energy Star tests need to verify that the input AC voltage contains the distortion rate of the 13th-order harmonic component to be less than 2%. The 66202 digital power meter also provides a setting that allows the user to define the harmonic order N.
The user can set a current level to trigger the time point A at which the current measurement starts, and another parameter delay (DELAY) can be set to delay the time to actually capture the current waveform, which can help ignore the initial failure The required crest B. There is another parameter TIME, which is the length of time to capture the waveform, so that the 66202 digital power meter will measure the peak current at point C.
Provide graphical control software, control and read data on the computer through USB or GPIB interface, can also observe the voltage and current waveforms, record the relationship graph with time, and can also save the long-term measurement value to a file for analysis , In line with Energy Star‘s requirement that the measurement lasts 5 minutes per second, and then the average value is taken. Even 66202 can measure harmonic components and perform pre-testing work for IEC61000-3-2 current harmonic limits.
In addition, the power efficiency test software is provided, which integrates the 66202 power meter, electronic load and AC power supply. After simple settings according to Energy Star specifications, the test can be automatically performed according to the legal steps and reports are generated, which is quite suitable for R&D and quality assurance The unit‘s verification use of the power supply.
A662003 measuring fixture set (250V/10A) can be purchased to facilitate wiring test. 66202 can choose 50A/100A external current converter to increase the current measurement range.
