PWM DC Motor Speed Controller 9V 12V 24V 36V 48V DC 9V - 55V Pulse Width Modulation Regulator 20A 1200W Stepless Variable Speed

• Input supply voltage: DC 10V-55V;Maximum current: 60A;Continuous current: 20A;Speed range: 0-100%
• Potentiometer with switch function,High power speed controller switch which is much more adaptable.
• DC10V-55V PWM Brushed DC Motor Speed Controller Adjustable Driver CW CCW Reversible Switch With Digit Display
• Outer casing: it is designed to protect the controller board from damage as well as dissipate heat
• The input voltage must differentiate "+" ,"-",The input voltage should be equal to the rated voltage of the motor within 10-55V,or it will be burnt.
