Motor Speed Controller PWM Switch Electronic Regulator Module High Power Driven DC10-60V 20A 1. Wide Voltage Range: The input voltage of the motor speed controller is DC10-60V, suitable for 12V 24V 36V 48V and other common voltages.2. PWM control method: 1200W high mechanical drive module uses PWM method to control the speed of DC motor.3. For brushed DC motor: the output limit current of the motor speed controller is 20A, which is suitable for brushed DC motors.4. With Potentiometer: Equipped with a potentiometer, and the module has a standard mounting opening, which is safe and convenient to operate.5. Convenient wiring: barrier terminal type is adopted, which is convenient and quick for wiring and does not occupy space. Specification: Item type: switch motor speed controller Input voltage: DC10-60V Output voltage: linear at load Output limit current: 20A (use 10A for a long time , within 450W, pay attention to the module to dissipate heat) Final power: 1200W Speed regulation type: current regulation Speed regulation method: potentiometer (linear) Speed regulation duty cycle range: 0-Control frequency: 25KHZ Wiring type: terminal block barrier Knob wire length: approx .20cm/7.9in Module Size: Approx. 77 x 45 x 28mm / 3 x 1.8 x 1.1in Motherboard Installation Size: Approx. 73 x 40mm / 2.9 x 1.6in Potentiometer Installation Hole: Approx. 7mm / 0.3in Package List: 1 x DC Motor Speed Controller 1 x Potentiometer 1 x Knob Note: 1. Make sure the positive and negative connections are correct before turning on the power. Do not touch the heat sink with wiring, which may burn the circuit board. Please note that this is not a power module, it must be connected to the motor to adjust the speed, and the multimeter output will not change if the motor is not connected.2. This speed controller is used for brushed DC.3 motors. Not suitable for speed regulation of brushless DC motors; Neither can be used as a voltage regulator or regulator!
