With speed control switch for forward and rotation
DC motor speed controller
Product features:
High performance DC motor speed controller, without harsh whistling sound, with sufficient materials, high power, low heat generation, high efficiency, and large torque.
The governor adopts high-grade sealed potentiometer with switch function and positive and negative rotation control. Its price is three times that of ordinary potentiometer. Ordinary potentiometer is not dust-proof, and the speed regulation is easy to jump and unstable after a period of time.
Both the power transistor and voltage regulator are imported from the original factory. At high voltage, domestic voltage regulators cannot withstand it at all, so the power transistor and voltage regulator of this product are almost not damaged (except for non-human factors)
