■ Features High Airflow, High Static Pressure, and Long Service Life This fan features a maximum airflow of 3.70 m3/min, maximum static pressure of 430 Pa, and service life as long as 100,000 hours.(1) The maximum airflow has increased by 68% compared with our current model(2). Water and Dust Resistance Its IP68-rated(3) water and dust protection ensures stable fan operation even in harsh environments. High Energy Efficiency and Low Noise The PWM control function enables the external control of fan speed, contributing to lowering noise and improving energy efficiency of devices. (1) The values are for 9WL09^^P1H^^^ models, where □'s are wildcard characters. (2) Current model: San Ace 92W9WL type 92 x 92 x 25 mm Splash Proof Fan (model no. 9WL0912P4J001). (3) The degree of protection (IP code) is defined by IEC (International Electrotechnical Commission) 60529 as below. IP68: ■ Completely protected against dust ■ Protected against submersion in water 92x92x38mm The models listed below have pulse sensors with PWM control function. * PWM frequency: 25 kHz. Fan does not rotate when PWM duty cycle is 0%. Models with the following sensor specifications are also available as options: Without Sensor

92 × 92 × 38 mm ■ PWM Input Signal Example Input signal waveform VIH = 4.75 to 5.25 V　VIL = 0 to 0.4 V PWM duty cycle (%) = T ×100 PWM frequency 25 (kHz) = T Current source (Isource) = 1 mA max. (when control voltage is 0 V) Current sink (Isink) = 1 mA max. (when control voltage is 5.25 V) Control terminal voltage = 5.25 V max. (when control terminal is open) When the control terminal is open, fan speed is the same as when PWM duty cycle is 100%. Either TTL input, open collector or open drain can be used for PWM control input signal. ■ Example of Connection Schematic ＋ ○ 10 kΩ Control PWM input...
