How to ensure that the power supply works for a long time—PA power analyzer

The PA power analyzer can accurately measure the output voltage, current, power, harmonics and conversion efficiency of the power supply. Zhiyuan's PA5000H power analyzer has 0.05% power measurement accuracy, 5MHz bandwidth and rich harmonic measurement functions and is widely used R&D and testing of power supply products.

Power analyzer—electrical parameter testing

The power analyzer focuses on steady-state testing. The power analyzer can test AC input and DC output at the same time, conduct synchronous analysis of overall energy efficiency and electrical parameters, and test input and output voltage, current, test voltage, current effective value, power factor, Efficiency, harmonics, etc., as shown in Figure 1.

Power analyzer—efficiency and power factor testing

The power analyzer tests the AC input power and DC output power, and sets the electronic load from no load to full load. Using the XY display mode of the power analyzer, you can directly test the efficiency and power factor curves from no load to full load.
