DC Fan ■ Features Low Noise Compared to our current model,(1) noise level has been reduced by 3 dB(A). High Cooling Performance While featuring low noise, the maximum airflow and maximum static pressure have increased by 33% and 70%,(2) respectively, compared to the current model.(1) Energy Saving Power consumption has been reduced by 35% compared to the current model.(1) Rich Lineup The lineup offers four different rotational speeds for each of 12/24/48 V rated voltages. The broad lineup of fans enables you to choose the right fan best suited to your applications. (1) Current model: 140 × 140 × 38 mm San Ace 140 9P type DC Fan (model: 109P1448H101). (2) For models 9RA1412P1G001, 9RA1424P1G001, and 9RA1448P1G001. The models listed below have ribs and pulse sensors with PWM control function. For models without ribs, append "1" to the end of model numbers. Model no. Operating voltage range [V] The models listed below have ribs and pulse sensors. For models without ribs, append "1" to the end of model numbers. Model no. Operating voltage range [V] Models with the following sensor specifications are also available as options: ■ Common Specifications □ Material □ Expected life Frame: Plastic (Flammability: UL 94V-0), Impeller: Plastic (Flammability: UL 94V-0) Refer to specifications (L10 life: 90% survival rate for continuous operation in free air at 60°C, rated voltage) Expected life at 40°C is for reference only. □ Motor protection function Locked rotor burnout protection, Reverse polarity protection 50/60 Hz, 500 VAC, for 1 minute (between lead wire conductors and frame) 10 MΩ min. at 500 VDC (between lead wire conductors and frame) □ Sound pressure level (SPL) A-weighted sound pressure level (SPL) at 1 m away from the air inlet. Refer to specifications (Non-condensing) ＋ Red − Black Sensor Yellow Control Brown (For models without PWM control function, there is n

140 × 140 × 38 mm ■ PWM Duty - Speed Characteristics Example Voltage: 12 VDC PWM frequency: 25 kHz ■ 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...
