Pulse Width Modulated DC Fans

Application of PWM Speed Control

JMC offers a host of high frequency Pulse Width Modulated (PWM) fans that perform at low noise levelsApplication of PWM Speed Control by eliminating the power switching noise of the fan. The motor commutation noise is eliminated with high frequency PWM as the coils of the fan are being switched with a frequency above 20 kHz, which is outside the human audible range.

The speed of the fan is controlled by an external PWM signal. The JMC PWM ramps up linearly from a 20% duty cycle up to the fan’s maximum rated speed.

All fan sizes are in millimeters (“mm”).
Also available in 24 and 48 Volts
FV – Fixed Vane style
CR – Counter Rotating dual fans
Data table reflects HIGH speed PWM Fans
All performance figures are at nominal voltage
