By Puls width modulation (PWM) 0 ... 100%
Open collector in relation to signal-ground
f = 2kHz +-20%
Transistor requirements:
Vce max. >= 12V; Isink max. >= 5mA
Vce sat. <= 0,15V
Information to the curve:
0 % - 5% PWM: 0 1/min
5 % - 10% PWM: 500 1/min (corresponding to min. speed)
10 % - 90% PWM: linear increasing curve
90 % - 100% PWM: 3.850 1/min (corresponding to max. speed)
5 % PWM: 500 1/min bzw. 0 1/min (Fan off, comming from 100% PWM)
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.
Measurement setup: Measured between two steel plates
Steel plate: 180 mm x 180 mm
Intake nozzle: D: 94 mm; R: 16 mm
Distance between bottom and top plate: 60,6 mm
Overlapping impeller / nozzle: 0,3 mm
∆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
