Information to the curve:
0 % - 7% PWM: 0 1/min
7 % - 10% PWM: 800 1/min (corresponding to min. speed)
10 % - 90% PWM: linear increasing curve
90 % - 100% PWM: 5.400 1/min (corresponding to max. speed)
7 % PWM: 800 1/min (Fan on, comming from 0% PWM)
5 % PWM: 600 1/min or 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: 125,5 mm; R: 10 mm
Distance between bottom and top plate: 64,5 mm
Overlapping impeller / nozzle: 2 mm
∆p = 0: corresp. to free air flow (see chapter aerodynamics)
I: corresp. to arithm. mean current value
Name Condition
PWM 0001 PWM: 100 %; f: 2 kHz
The data at 50% are no FK features and need not be tested.
Electrical operating data with intake nozzle (for test purposes) according to 10pcs protocol at plant
Herbolzheim.
