PWM DC Motor Speed Controller for Brushed Motors - DIY & Robotics

Product Description

Feature:1. Using PWM speed control technology, high conversion efficiency, wide speed control range, stable performance.2. Imported semiconductor chips are used and tested in terms of voltage, current, function, etc., the circuit is stable and reliable.3. Potentiometer can be used to accelerate the positive and negative switches of forward, reverse and stop.4. Safe to use, with overload and short circuit protection to protect the motor from damage and prolong the service life of the motor.5. Wide speed range, reaching 5% to 95%, PWM frequency 500Hz, potentiometer resistance value B10K.Specification:Item Type: DC Motor Speed ControllerMaterial: Printed Circuit BoardPurpose: For DC Motor Speed AdjustmentModel: CCM2Working Voltage: DC10V-30VControl Power: 12V x 3A=36W, 24V x 3A=72W, More Than 24A, Maximum 120WRated Current: 3AMaximum Current: 4ASpeed Adjustment Range: 5%-95%PWM Frequency: 500HzPotentiometer: Resistance Value B10KCable Length: Approx. 20cm / 7.9inOutput Voltage: About 0-100% of the Input VoltageProduct Size: Approx. 74 x 47 x 28mm / 2.9 x 1.9 x 1.1in Package List:1 x DC Motor Speed Controller1 x Switch1 x Knob1 x Nut1 x WasherNote:1. The input of the DC motor speed controller is DC, and it cannot be directly connected to AC power (such as household 220V AC motor), otherwise it will burn out.2. The positive and negative poles of the DC power supply cannot be reversed, otherwise the governor will be damaged.3. The motor can be positive or negative. When the running direction is inconsistent with the expectation, the direction can be changed by adjusting the wire sequence.4. The potentiometer knob can change the duty cycle of the governor output, thereby changing the motor speed.
