San Ace 80 9RA type DC Fan ■ Features Low Noise and Energy Saving Compared to our current model,(1) noise level has been halved(2) and power consumption has been reduced by 41%.(3) Moreover, the models with PWM control, which enables the control of fan speed, provide further optimized noise level and efficiency. Long Life This fan lasts 1.5 times longer than the current model,(1) and is capable of continuous operation for 60,000 hours (approximately 7 years), improving the maintainability. Rich Lineup The product lineup is available in a wide variety in 12/24/48 voltage, cooling performance, noise level, and PWM control. This allows users to choose the most suitable one for their applications. (1) Current model: 80 x 80 x 25 mm San Ace 80 9R type DC Fan (model: 109R0812G401). (2) A 3 dB(A) decrease in noise level. 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. Models with the following sensor specifications are also available as options: Without sensor Lock sensor

80 × 80 × 25 mm ■ PWM Duty - Speed Characteristics Example (min-1) 5000 ■ 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) VIL 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 of Connection Schematic Rated voltage 12 V fan...
