■Features
Low Power Consumption
The power consumption has decreased by 45% compared with
our current model.*
High Static Pressure
The static pressure has increased by 63% compared with our
current model.*
Low Noise and High Energy Efficiency
The PWM control function enables the external control of fan
speed, contributing to lower noise and higher energy
efficiency of devices.
* Our current DC fan model 9GV1212P4G01, 120 x 120 x 25 mm "San Ace 120 9GV type".

VIH = 4.75 to 5.25 V　VIL = 0 to 0.4 V
PWM duty cycle (%) = PWM frequency 25 (kHz) =
Current source (Isource) = 1 mA max.(when control voltage is 0 V)
Current sink (Isink) = 1 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.

■Features
Low Power Consumption
The power consumption has decreased by 45% compared with
our current model.*
High Static Pressure
The static pressure has increased by 63% compared with our
current model.*
Low Noise and High Energy Efficiency
The PWM control function enables the external control of fan
speed, contributing to lower noise and higher energy
efficiency of devices.
* Our current DC fan model 9GV1212P4G01, 120 x 120 x 25 mm "San Ace 120 9GV type".
