210 Pa,
(1)
which are about 1.68 times and 3.19 times higher than our current model,
(2)
respectively.
Low Noise and Energy Saving
The PWM control function enables the control of fan speed, contributing to lowering
noise and improving energy efficiency of devices.
Water and Dust Protection
This fan achieves excellent IP68
(3)
water and dust protection, maintaining stable
operation in harsh environments.
(1) For models 9WPA0412P6G001 and 9WPA0424P6G001
(2) Current model: 40 × 40 × 20 mm San Ace 40W 9WP type Splash Proof Fan (model no. 9WP0412H6001).
(3) The degree of protection (IP code) is defined by IEC 60529 (International Electrotechnical Commission)
as follows.
The protection rating applies only to electrical components (motor coils and electronic components) in
our fans.
The mechanical components other than the electrical components are not subject to protection.

PWM duty cycle (%) = PWM frequency 25 (kHz) =
Current source (Isource) = 1.0 mA max. (when control voltage is 0 V)
Current sink (Isink) = 1.0 mA max. (when control voltage is 5.25 V)
When the PWM control terminal is open,
the fan speed is the same as the speed at 100% PWM duty cycle.
The PWM signal can be used with open collector or drain input.
Note that when using an open collector or drain input,
or inputting a different voltage or frequency,
the speed relative to the PWM duty cycle may differ from this specification.
