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:
