Test mode points three kinds of commonly used cooling fan
1, the constant voltage mode: specify mode or set, respectively, in the morning, a cooling fan can be made for the customer a variety of cooling fan
a: specify the command mode or voltage according to finalize methods of output voltage.
b: set pattern directly input to perform voltage life value, morning of dongguan macro electronic technology co. , LTD. Professional cooling fan manufacturer.
2. PWM mode: refers to the fan in a fixed voltage state, at a different frequency and duty. Cycle to control its speed.
3, constant speed mode: execution of measured fan fixed speed setting value, because the speed is not easy for a fixed value, thus giving the appropriate value.
