0.05% power measurement accuracy

PA3000 power analyzer uses the advanced design platform architecture in the embedded field, from the front-end analog circuit design to DSP and FPGA high-speed arithmetic processing circuit design, and finally to the industrial X86 control technology, each of which we have done optimization processing, eventually make PA3000 reached the power measurement accuracy up to 0.05%.

1000V/50A, 7 elements direct measurement

PA3000 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 256th order

PA3000 power analyzers have the bandwidth of DC/0.1Hz-1MHz. 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).

Bivector graph analysis

PA3000 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.

60G data storage and excellent data format analysis

PA3000 power analyzer is equipped with a solid state disk (SSD) of 60G, which is capable to perform massive data storage. It can even allow users to connect the USB flash drive directly so as to store all the data needed. It supports a variety of formats such as PAD and CSV, and the storage time is controlled at will, thus storage is no longer an issue.
