Schematics
Input voltage divider:
R1 = 47 kOhm
R2 = 36 kOhm
Speed control:
By pulse-width modulation (PWM) 0 ... 100%
Open collector in relation to Signal-ground
Frequency = 2 kHz (1 - 10 kHz)
Push-Pull-Signal with high = 12 V
Information to the curve PWM:
0% - 10% PWM: 0 1/min
11% PWM: 1.000 1/min (Fan on, comming from 0% PWM)
11% - 13% PWM: 1.000 1/min (corresponding to min. speed)
13% - 82% PWM: linear increasing curve
82% - 100% PWM: 4.250 1/min (corresponding to max. speed)
9% PWM: 800 1/min or 0 1/min (Fan off, comming from 100% PWM)
