DC Fan ■ Features Low Noise and Energy Saving Compared to our current model,(1) noise level has been reduced by 3 dB(A) and power consumption has been reduced by 25.5%.(2) Moreover, the models with PWM control, which enables the control of fan speed, provide further optimized noise level and efficiency. Rich Lineup The product lineup is available in a wide variety in different 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 × 80 × 38 mm San Ace 80 9G type DC Fan (model: 9G0812G101).

80× 80× 38 mm ■ PWM Duty - Speed Characteristics Example (min-1) 9000 ■ 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 frequency, the speed relative to...
