PWM (Pulse-Width Modulation)

PWM (Pulse-Width Modulation)By R&D dept.

Pulse-width modulation (PWM) is to adjust working frequency generated from the internal components by using a pulse width modulated resulting in the variation of the average value of the waveform . Your computer or electric equipment's circuit can control the fan speed through TTL pulse signal (Hz) or amplitude signal of open-drain (V) for the most effective heat dissipation.
