■Features
High Static Pressure
The maximum static pressure has increased by 62% compared with our
current model*.
It provides effective cooling especially for high density equipment.
High Energy Efficiency and Low Noise
Power consumption and noise level have been reduced by approximately
10% and 3 dB(A), respectively, compared with our current model*.
Furthermore, the PWM control function enables the external control of fan
speed, contributing to even lower noise and higher energy efficiency of
devices.

VIH = 2.8 to 5.25 V VIL = 0 to 0.4 V
PWM duty cycle (%) = PWM frequency 25 (kHz) =
Current source (Isource) = 2 mA max. (when control voltage is 0 V)
Current sink (Isink) = 2 mA max. (when control voltage is 5.25 V)
Control terminal voltage = 5.25 V max. (when control terminal is open)
When the control terminal is open,
fan speed is the same as when PWM duty cycle is 100%.
Either TTL input, open collector or open drain can be used for
PWM control input signal.
