["Description:\r\n brand new,high quality\r\nFeatures:\r\nThe button is more precise than the traditional potentiometer, and has a long service life (1 million times). It does not automatically generate drift.\r\nThe digital display shows the value 001, 002, 003...100, which means the maximum running speed of the motor.\r\nStart slowly, reach the set speed, prevent the starting current from being too large, damage the power supply by instantaneous impact, damage the motor, damage the machine light and other unwanted phenomena.\r\nUsing single-chip technology to adjust speed is more smooth and smooth than traditional 555 chip, good linearity, low noise and long service life.\r\n\r\nSpecifications:\r\nItem Type: Motor Speed Controller\r\nMaterial: for Shell ABS\r\nInput voltage: 12V-24V DC\r\nPWM frequency: 15KHz\r\nSpeed adjustable range: 0%-\r\nWorking current: 5A\r\nWorking current: 8A\r\nWorking Power: 12VX5A=60W, 24VX5A=120W\r\nSize: 7x5x2cm/2.76x1.97x0.79in\r\nColor: Gray\r\nQuantity: 1 Pc\r\n\r\nThe display range of 3-digit LED display is \"000\"-\"100\". (For example, displayed \"055\", it means that the PWM output duty cycle is 55%.)\r\nSlow start function:\r\nWhen connect the power to start,the motor will reach the setting speed slowly,not reach immediately.it can avoid the instantaneous impact damage the power or motor.\r\n\r\nWARNING:\r\nDo Not Reverse Positive And Negative Power Loads. This Will Damage The Controller.\r\nTo Change Motor Direction, Interchange The Positive And Negative Wires of Motor.\r\nNo forward/reverse function.\r\n\r\nNote:\r\nTransition: 1cm=10mm=0.39inch.\r\nPlease allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.\r\nDue to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!\r\n\r\nPackage Includes:\r\n1 x Motor Speed Controller"]
