ACDC Fan ■ Features High Airflow and High Static Pressure These fans deliver a maximum airflow of 6.7 m3/min and a maximum static pressure of 195 Pa. Low Power Consumption Power consumption has been reduced by approximately 32% compared with the current model.* Also, the PWM control function enables the control of fan speed, contributing to lowering noise and improving energy efficiency of devices. Wide Operating Voltage Range These fans have an input voltage range of 100 to 240 VAC, supporting both 100 and 200 VAC systems. * For San Ace 172 AC Fan (Model 109S301) Lead wire model 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%. Terminal model 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%. Models with the following sensor specifications are also available as options: Without sensor! Lock sensor I Low-speed sensor [Sensor] Yellow [Control) Brown [GNP] Black

■ PWM Input Signal Example Input signal waveform VIH = 4.75 to 5.25 V　VIL = 0 to 0.4 V VIL When the PWM control terminal is open, the fan speed is the same as the speed at 0% PWM duty cycle. A TTL input can be used for the PWM input signal. ■ Example of Connection Schematic Inside of fan Isource Isink PWM input signal ■ Specifications for Pulse Sensors Output circuit: Open collector Inside of AC fan Pull-up voltage Photocoupler Pull-up resistor Sensor output Output waveform (Need pull-up resistor) In case of steady running (One revolution) T0 T1 VOH VOL 0V PWM duty cycle (%) = T ×100 PWM frequency...
