Splash Proof Centrifugal Fan ■ Features Water and Dust Protection Its IP68-rated111 water and dust protection, which is improved compared with that of our current model, ensures stable fan operation even in harsh environments.121 High Airflow and High Static Pressure This fan delivers a maximum airflow of 2.03 m3/min and a maximum static pressure of 708 Pa.131 Low Noise and High Energy Efficiency The PWM control function enables the control of fan speed, contributing to lowering noise and improving energy efficiency of devices. (1) The degree of protection (IP code) is defined by IEC 60529 (International Electrotechnical Commission) as follows. (2) Current model: San Ace 100W9W1TM type 0100 x 25 mm Splash Proof Centrifugal Fan ■ Specifications When the optional inlet nozzle (109-1080H) is mounted. The models listed below have pulse sensors with PWM control function. * PWM input frequency is 25 kHz; models without specifications at 0% PWM duty cycle have zero fan speed at 0%.

■ PWM Duty - Speed Characteristics Example (min-1) 8000 ■ 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 PWM control terminal is open, the fan speed is the same as the speed at 100% PWM duty cycle. Either a TTL input or open collector/drain input can be used for the PWM input signal. ■ Example...
