0.01% certified power measurement accuracy

PA8000 is a certified power analyzer with up to 0.01% power accuracy and 5MHz bandwidth. Used as the reference of energy efficiency tests for inverters, converters and power supply products, it is also the basis for laboratories to certify standard tests.

5MHz bandwidth for stable frequency characteristics and stability

PA8000 is the only power analyzer in the industry with up to 0.01% accuracy and up to 5MHz current and voltage frequency bandwidth, fully meeting the requirements of future power measurement of high-speed switching devices, such as sic.

High phase measurement accuracy under low power factors

PA8000 Power Analyzer has the bandwidth of DC/0.1Hz-5MHz. Thanks to the PLL source frequency-doubling technology, the harmonics measurement with faster speed and wider dynamic range has become realized. In harmonics mode, they can make accurate tests of fundamental voltage, fundamental current, power, phase, harmonic component and total harmonic distortion factor (THD).

1ms high data update rate

PA8000 is the only power analyzer in the world that data update rate can be set to 1ms.The 1ms~5ms high-speed data acquisition mode is added to PA8000. The 1ms data update rate can accurately capture the rapidly changing transient signals and perfectly display the waveform details. In motor applications, PA8000 is able to completely measure the startup waveform of the motor so as to provide important basis for users to assess the motor.

Phase compensation function of current sensor

When a current sensor is used as the input, the delay inherent to the sensor will increase the phase errors of the voltage and current. However, the phase compensation function of PA8000 can correct the phase error from the sensor and enhance the power measurement accuracy under the conditions of high frequency and low power factors so as to ensure the power measurement accuracy of the overall system.
