12-50V 30A 500W Adjustable Speed Controller Dc Brush Motor Speed Pwm Controller

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 12-50VRated Current: 30AControl Power: Max. 500WSpeed Control Range: 0% -100%PWM Frequency: 21KHzItem Size: 70 * 40 * 30mmQuantity: 1pc
 Features:Wide range of operating voltage: 12V 250W, 24V 350W, ... 48V 500WA 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:
