Storage temperature is -30C to +70C. For operating temperature range, see individual specification sheet. Switching with the PWM control may affect the sensor output. Specifications may be changed without notice. 289 Technical Material PWM Speed Control Function The PWM speed control function is a function that externally controls the rotation speed of the fan by changing the duty of the input pulse signal between the control terminal and GND. It regulates optimum airflow for efficient cooling when necessary, and is effective for lowering power consumption and reducing equipment noise level. * Some models can not have PWM speed control function.

( When control terminal is opened ) When the control lead wire is open, speed is same as one at 100% PWM duty cycle. This fan speed should be controlled by PWM input signal of either TTL input or open collector, drain input.
