SANYO DENKI San Ace 1331V Splash Proof Centrifugal Fan ■ Features Water and Dust Protection Its IP68-rated111 water and dust protection, which is improved compared with that of our current model,121 ensures stable fan operation even in harsh environments. High Airflow and High Static Pressure This fan delivers a maximum airflow of 6.39 m3/min and a maximum static pressure of 395 Pa. Low Noise and Energy Saving The PWM control function enables the control of fan speed, contributing to lowering noise and improving energy efficiency of devices. (1) The degree of protection (IP code) is defined by IEC 60529 (International Electrotechnical Commission). (2) Current model: 0133 x 91 mm San Ace 133W9W1TJ type Splash Proof Centrifugal Fan ■ Specifications When the optional inlet nozzle (109-1069H) is mounted. The models listed below have pulse sensors with PWM control function. * PWM input frequency is 25 kHz. Models without specifications at 0% PWM duty cycle have zero fan speed at 0%. Note: Max input is 45 W at rated voltage. Motor case: Aluminum (Black coating), Impeller: Plastic (Flammability: UL 94V-0) Refer to specifications (L10 life: 90% survival rate for continuous operation in indoor free air at 60°C, rated voltage) Expected life at 40°C is for reference only.

■ PWM Input Signal Example Input signal waveform VIH = 4.75 to 5.25 V　VIL = 0 to 0.4 V 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 DC fan input voltage Inside of DC fan 5V 5.1 kΩ Control PWM input signal ■ Specifications for Pulse Sensors Output circuit: Open collector Inside of DC fan Pull-up resistor Pull-up voltage Ic Sensor output (VCE) Output waveform (Need pull-up resistor) In case of steady running (One revolution)...
