■ Features High Static Pressure, High Airflow, and Long Life This fan delivers a maximum static pressure of 1780 Pa and a maximum airflow of 0.93 m3/min.(1) Compared with our current model,(2) the maximum static pressure has increased by 8.6 times and maximum airflow has increased by 1.8 times. This fan offers greatly improved static pressure and airflow while maintaining the long service life of the current model. Low Noise and Energy Saving The PWM control enables the control of fan speed, contributing to lowering noise and improving energy efficiency of devices. (1) For models 9LG0412P3G001 and 9LG0424P3G001. (2) Current model: 40 x 40 x 28 mm San Ace 40L 9L type Long Life Fan (model: 9L0412J301). Models with the following sensor specifications are also available as options: Without sensor Lock sensor The models listed below have a pulse sensor with PWM control. * PWM frequency is 25 kHz. Models without ratings for 0% PWM duty cycle have zero speed at 0%. When control terminal is open, speed is the same as at 100% duty cycle. Frame: Aluminum (Black coating), 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.

40 × 40 × 28 mm ■ PWM Duty - Speed Characteristics Example (min-1) Voltage: 12 VDC 40000 PWM frequency: 25 kHz 35000 ■ 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) = 1.0 mA max. (when control voltage is 0 V) Current sink (Isink) = 1.0 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...
