Transistor requirements: VCE max. >= 12V; Isink max > 5mA; VCEsat < 0,15V
Alternatively to the PWM signal the fan can be controlled by an analog control signal of 0...5 V (5 V corresponds to
100 % PWM)
It must be ensured that the power supply is "sink-able" and can operate with the internal pull-up resistor.
The shown pull-up resistor to the internal reference voltage (+5V) has 10kOhm.
3.2 Electrical Operating Data
Measurement
conditions:
Normal air density = 1,2 kg/m3; Temperature 23°C +/ - 3°C; Motor axis horizontal; warm-up
time before measuring 5 minutes (unless otherwise specified). In the intake and outlet area
should not be any solid obstruction within 0,5 m.
∆p = 0:
corresp. to free air flow (see chapter aerodynamics)
I:
corresp. to arithm. mean current value
Name Condition
PWM 0001 PWM: 95 %; f: 2 kHz
Attention!
The inrush current depends on the capacitor and the resistance of the wires. When using an external capacitor the
inrush current rises accordingly. The integrated capacitor has 47uF.
