## **9W1B type** 

## **Splash Proof Blower** 

■ **Features** 

## **High Static Pressure and High Airflow** 

This blower delivers a maximum static pressure of 540 Pa and a maximum airflow of 1.09 m3/min.* 

Blowers can send out straight airflow with high static pressure, making them suitable for localized and spot cooling applications. 

## **Water and Dust Resistance** 

Its IP68-rated** water and dust protection ensures stable fan operation even in harsh environments. 

## **High Energy Efficiency and Low Noise** 

The PWM control function enables the control of fan speed, contributing to lowering noise and improving energy efficiency of devices. 

- These values are for models 9W1BM12P2H001 and 9W1BM24P2H001 

- ** The degree of protection (IP code) is defined by IEC 60529 (International Electrotechnical Commission). IP68: 

- ・Completely protected against dust 

- ・Protected against submersion in water 

## **97× 33 mm**

## ■ **PWM Input Signal Example** 

Input signal waveform

T1 1 PWM duty cycle (%) = T PWM frequency  25 (kHz) =×100 T 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.
