9B1TP type
Bracket-mounted Centrifugal Fans
■ Features
Maximizes Strengths of the Centrifugal Fan
To maximize fan performance, an air inlet needs to be
precisely mounted to the fan.
Bracket-mounted centrifugal fan has an air inlet and a
mounting bracket integrated in one unit. The precise
assembly at factory ensures the optimized balance, helping
the fan perform at its maximum potential.
Easy Installation
Centrifugal fan comes equipped with an air inlet and a
mounting bracket, making your installation work easy.

T1
×100
T
PWM frequency 25 (kHz) = 1
T
Source current (Isource) : 1 mA max. at control voltage 0 V
VIH
PWM duty cycle (%) =
Sink current (Isink) : 1 mA max. at control voltage 5.25 V
VIL
Control terminal voltage: 5.25 V max. (Open circuit)
T1
When the control lead wire is open,
the fan speed is the same as the one at a PWM duty cycle of 100%.
Either TTL input, open collector or open drain can be used for
PWM control input signal.
