【Example】
Fans with the PWM control function
■ Available size and example of characteristics
The numerals on *marking depend on each fan spec. Please ask us if you need those details.
Please ask us about speed at 0% duty cycle .
It should be 0 to 30% speed of rated speed as a rough target.
Tach outout is embedded for all the standard part numbers.
