This 12V DC PWM controller features a 5 inches(12.7 cm) long connection to its potentiometer. The potentiometer has a on/off switch built-in with a knob. An overload protection is set at 10 amps of current so the controller will shut down when such a current occurs. The distance of the connection wires between the motor and the controller is 10 inches(25.4 cm). The distance of the 12v connection wire is 46 in(116.8 cm) long.
This controller works with Makermotor's PN01007 and PN00113 series.
Features: Reverse polarity protection built in, 10A rating
Construction: Extruded aluminum housing with 2 mounting tabs
Input Voltage: 12-15vdc
The product works well and as advertised.
The only negative issue is that it cost just under $100 CDN with shipping and delivery charges included!
I bought this speed control for a 12v 3/8 shaft 50 rpm gear. I was impressed with the quality and response. I highly recommend it.
