A selected combination of machines and UPS might or might not have an issue. Distinct UPS types make diverse simulated wave variety styles, unique power provides have distinct sensitivity for the waveform form, diverse equipment configurations have distinct power load vs. UPS potential, etcetera.
The large peak with เครื่องสํารองไฟ apc the left fringe of the spectrum plot could be the sixty Hz essential. The big harmonic peaks you see show that my wall power here just isn't Tremendous-clean.
