Because of the export relationship, the input voltage and frequency of household appliances manufacturers are often different from those of local appliances in the region where they are exported. The products often carry out accelerated life and aging experiments. Therefore, power supply equipment with pure waveform, very low harmonic distortion, stable voltage and frequency has become an indispensable and important part of manufacturing, research and testing for manufacturers. Not only can it greatly improve the power environment of the power grid, but also can provide simulation of the power environment of all kinds of power grids. Excellent household appliances and motor products are increasingly inseparable from the assistance of power equipment with superior performance. Especially for electrical appliances such as motors and compressors, because of their unique backfilling characteristics, the requirements for power supply equipment are higher. It is necessary to provide a high reliability, high stability, low interference and low distortion power environment for pull-offs test.

If the power quality of power grid environment is not ideal, AVR APA6000 series can be selected to improve, greatly reducing the impact of power grid fluctuation on testing.
