Splash Proof Fan ■ Features High Static Pressure This fan delivers a maximum static pressure of 555 Pa,(1) which is about 1.38 times higher compared to our current model.(2) 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 9WPA0412P3G001 and 9WPA0424P3G001 (2) Current model: 40 × 40 × 28 mm San Ace 40W 9WL type Splash Proof Fan (model no. 9WL0412P3J001). (3) The degree of protection (IP code) is defined by IEC 60529 (International Electrotechnical Commission) as follows. The models listed below have ribs and pulse sensors with PWM control function.

40 × 40 × 28 mm ■ PWM Duty - Speed Characteristics Example (min-1) 24000 ■ PWM Input Signal Example Input signal waveform PWM duty cycle (%) = T ×100 PWM frequency 25 (kHz) = T 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...
