1000V/50A, 7 elements direct measurement

PA5000 Power Analyzer makes use of a 100MHz synchronous clock with high-stability temperature compensation to avoid the measurement error caused by temperature drift, keeping the phase error of each element within 10ns to ensure accurate measurement of active power and power factors.

Harmonics up to 500th order

PA5000 power analyzer has a bandwidth of up to 5M and sampling rates up to 2 MS/s, which can measure harmonics up to 500th order. It also features multiple combined display modes to display each harmonic component at the same time. Users can click the "First Ten Harmonics Function" in the menu to check the top ten harmonics with highest energy among all harmonics. Moreover, in order to facilitate users analyzing in more details, we add the FFT harmonic analysis function. Through this function, users can check each frequency value and each interharmonic data.

Dual PLL source, frequency-doubling technology

PA power analyzer synchronizes the sampling frequency with the signal frequency by incorporating the PLL hardware circuit so as to obtain accurate results of harmonics measurement. Moreover, this function is upgraded in PA8000 and PA5000 Power Analyzer, which supports dual PLL source so that users can select different PLL sources for different measurement elements to facilitate the contrastive analysis on the harmonics of input and output signals simultaneously.

Multi-motor test

Any one or several of the 7 power boards of PA5000 power analyzer can be upgraded to motor test board(s) (multiplex motor boards are also available for PA8000 and PA5000). Through the power board paired with the motor board, the gearbox (inverter) and motor inside the electric vehicle can be jointly debugged and tested so that users can measure the overall performance of the motor system more precisely.

Bivector graph analysis

PA5000 power analyzer can measure and display the vector graph of the inverter’s three-phase input and output at the same time, and analyze the phase angle between each input and output phase so as to precisely assess the impact that the angular difference of the input signal has on the output signal.(For all models)

60G data storage and excellent data format analysis

PA5000 power analyzer is equipped with a solid state disc (SSD) up to 60G for massive data storage. Users can directly connect the USB flash drive to it to store all the needed data. It supports multiple formats, such as PAD and CSV. With the storage time controllable, storage is no longer a problem.
