A. Connection for maximum speed
B. Connection for adjustable speed using an external potentiometer:
– 10 V > n = maximum
– 1 V > n = minimum
– <1 V > “n = fan stops
C. Connection for adjustable speed via PWM (pulse with modulation) (1–10 kHz):
– 100% PWM > n*maximum
– 10% PWM > n*minimum
– <10% PWM > n = 0
D. Imax (maximum current) = 10 mA
E. Connection if using internal potentiometer (B)
