30A 3-phase Brushless Motor PWM Control Speed Controller Bullet Point

Safe boot,temperature protection,Programmable,High Power,Brake,linear recognition

This controller is design for High power High speed DC brushless motor

This DC12V governor (JCF1201 type) can be controlled according to the ambient temperature of the fan speed, no manual control, automatic stepless speed, the higher the ambient temperature, the faster the fan speed control

Fit for 2,3,4 line 12V fan, stepless temperature control can be achieved.

Single temperature sensor, easier to use, more responsive control.
