12-50V 30A 500W ADJUSTABLE SPEED CONTROLLER DC BRUSH MOTOR IN SOUTH AFRICA

12-50V 30A 500W Adjustable Speed Controller DC Brush Motor Speed PWM Controller Adjuster with Control Switch   It's a PWM speed controller so it enables you to control the speed of these little DC brush motors smoothly.  It's ideal for applications like fans, etc. providing nice adjustment of motor speed instead of the more usual "High-Low" switching   Specifications: Operating Voltage: DC 12-50V Rated Current: 30A Control Power: Max. 500W Speed Control Range: 0% -100% PWM Frequency: 21KHz Item Size: 70 * 40 * 30mm Quantity: 1pc   Features: Wide range of operating voltage: 12V 250W, 24V 350W,... 48V 500W A good speed controller for DC brush motors. High-frequency capacitance, power tube and 10A fuse are used in the module. Adopts sealed and high-quality potentiometer with switch, stable performance. Metal case creates better durability; high efficiency and low noise. Suitable for applications like fans, etc. providing nice adjustment of motor speed.   Warning: 1. This speed controller is applicable to DC brush motor, not the DC brushless motor; it can't be used as voltage regulator. 2. It should be connected with DC voltage, don't connect with AC voltage(e.g. 220V AC). 3. It can not use the 48V battery, battery power supply (48V storage electrical voltage of more than 50V.) 4. The anode and the cathode of DC power cannot be connected reversely, otherwise the controller will be damaged. 5. When running direction is inconsistent with your desire, you can change it by adjusting the linear order. 6. Potentiometer switch can change the output duty cycle of controller and then change the motor speed.   Package Includes: 1 *  DC Motor Speed Controller   More Details:
