The first is the soft start protection of the delay, which can be extremely stable during the process from start to full speed, so that the mechanical system of the motor and the locomotive is well protected. Secondly, it has the protection sequence protection. If the actual operation sequence is wrong, then the locomotive will not start, avoiding the operator's wrong operation behavior; the other is overvoltage and undervoltage protection; effectively prevent the voltage from starting. If the motor is too high or too low, the motor will be seriously damaged; it has a current protection function; the current sensing technology is used to track and detect the motor current in real time. If the current is continuously increased due to the overload of the locomotive or the failure of the locomotive, the current protection circuit operates to reduce the speed of the locomotive in time, and the motor and the mechanical system are effectively protected. It has the function of anti-reverse protection of power supply; if the polarity of the battery is reversed, the control box will stop and the power components will be protected from damage. It has temperature protection function; if the chopper operating temperature is the same as the set value, it will protect the circuit action and prevent the damage of the power component.
