RioRand 8-50V DC Motor Speed Controller for Power Wheel PWM Switch 5A 20A 30A

Added new functions: time delay protection and current protectionFor the childrens car, the current protection and protection delay functions are added.The protection current can be adjusted in 6 grades from 5A to 10A to 30A. The protection response time and delay can also be adjusted into 6 grades: immediate delay 1 second, 2 seconds ---- 5 seconds.Suitable for motors with different power and different currents.Example:There is a stroller, the power is not large, the protection current can be set to 5A or 10A, when the stroller is in practical application, such as stuck uphill, the current will increase, if the current reaches 5A, it exceeds the preset overload. The current will be protected and disconnected at this time, so that the drive will not be damaged due to stuck rotor/excessive time/overcurrent.ZS-X8 DC brush controller instruction manualFeatures:There is a potentiometer on the board for speed regulation. It supports 0-5V analog input corresponding to a duty cycle of 0-100% stepless speed regulation. The default PWM frequency is 12KHZ. There are K1 and K2 function buttons.Short press the K1 key to switch between with and without PWM output.Press and hold the K1 key for 4 seconds to switch between the two mimic inputs, the LED flashes slowly 2 times mimic input one (0.2-4.8V) input is valid, corresponding to duty cycle 0-100% stepless speed regulation. 4 times LED flashes slowly mimic input two (1-4.2V) is valid corresponding to duty cycle 0-100% stepless speed regulation (this parameter is mainly used with Hall handle), automatically saved after switching Power failure memory, the first power default 0.2-4.8V input is valid.Short press the K2 key to set the output current overload protection value. The default overload current is 20A. When the output current reaches 20A, the LED indicator will flash slowly. When the overload current is released, the LED indicator will return to normal and keep on. Increase, when it reaches 1.2 times of the set value, the protection will act, the output will be turned off, and the LED indicator will flash quickly. At this time, short press the K1 key or power off and restart to release the output protection, and the indicator will flash quickly and return to normal and long-light power indication.Short press the K2 key once to increase the output overcurrent protection value, a total of 6 gears can be selected. Each additional gear is 5A, the minimum gear is 5A, and the maximum gear is 30A. For example, the default is 4 gears and 20A. At this time, short press the K2 button once. After the indicator light flashes slowly 5 times, it means to increase the first gear to 25A, and then short press the 2 key once, the indicator light flashes slowly 6 times, it means to increase the first gear to 30A, and then short the 2 button
