Professional manufacturing and production of radiator cooling fans, condenser fans and fan motors, etc.

Test mode points three kinds of commonly used cooling fan

Cooling fan test mode commonly used three kinds of

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.
