The Introduction of PWM - Antec April 15, 2022

PWM is the acronym for Pulse Width Modulation. It is a way to control analog devices with a digital output. Another way to put it is that you can output a modulating signal from a digital device such as an MCU to drive an analog device. It’s one of the primary means by which MCUs drive analog devices like variable-speed motors, dimmable lights, actuators, and speakers. PWM is not true analog output, however. PWM “fakes” an analog-like result by applying power in pulses, or short bursts of regulated voltage.

Many of our PC cases, including the latest FLUX Series PC cases, have a pre-installed ARGB & PWM controller. If you don't know how the PWM works, we are happy to walk you through it.
