4.1 Fan operation with speed controller
•
You must use a speed controller in order to operate
this fan. We include a digital speed controller in set
with the fan.
•
Locate the speed controller port under a screw-on
plastic dust cap on the side of the fan.
•
Controller – 8 speed digital speed controller. Each press
of a button on the controller increases the speed by 1
level or 12.5%. Speed level 1 = 12.5% of maximum speed,
Level 2 = 25%, Level 3 = 37.5%, Level 4 = 50%, Level
5 =62.5%, Level 6 = 75%, Level 7 = 87.5%, Level 8 = 100%
(maximum speed).
4.2 Optional speed controllers
•
PWM controllers (Arduino, Raspberry Pl, etc.) use
the frequency range of 15-32 kHz and voltage range
of 10-12 V.
•
If used with a third-party speed controller, use the
provided TRRS 3.5 mm connection wire or a DIY speed
controller wire with pin outputs to connect the fan with
the controller
•
Refer to the illustration below for a description of pin
outputs on the DIY speed controller wire.

4.4 Speed controller wire
•
Insert speed controller
wire jack fully into the
connection port until it
clicks into position. Secure
in place with a plastic
locking nut located on the
speed controller wire.
•
This fan is rated for continuous use and can be operated 24/7.
