Reversible Flow Fan ■ Features High Airflow and High Static Pressure This fan delivers a maximum airflow of 2.10 m3/min and a maximum static pressure of 285 Pa.(1) Compared to our current model,(2) the maximum static pressure has increased by approximately 2.8 times. Fewer Fans Required The fan's speed and blowing direction can be freely controlled by a PWM signal. By replacing multiple conventional fans with a single unit, this fan can contribute to cost reduction and space saving. Moreover, noise reduction or high efficiency can also be achieved by appropriately controlling fan speed. Same Level of Blowing Performance in Either Direction Almost equivalent airflow and static pressure performance can be obtained in either blowing direction. This eliminates the need to take the performance difference between two blowing directions into account in designing systems. (1) The values are for models 9RFA1312P3G001 and 9RFA1324P3G001 when blowing in the forward direction.

■ PWM Duty - Speed Characteristics Example Voltage: 12/24 VDC PWM frequency: 25 kHz Forward Reverse ■ 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...
