(PWM) Pulse Width Modulated DC Fans
Rexus offers Pulse Width Modulated (PWM) fans that perform at low noise levels by eliminating the power switching noise of the fan. The speed of the fan is controlled by an external PWM signal. The PWM ramps up linearly from a 20% duty cycle up to the fan's maximum rated speed. Because the fan can run at lower speeds it is more energy efficient and will therefore have a longer life.
