The opposite main form of power supply regulation will be the linear regulator, which usually suppresses minimal-frequency enter sound and เครื่องสํารองไฟ apc ร้อง ripple by 80-100 dB. Which means a bit of input bumpiness is going to arrive out of the filtering and regulation phases as just a certain amount of fuzz.
