Mine Explosion-proof and Intrinsical Safe Frequency Converter is a set of vacuum magnetic starter with digital frequency control devices of high-tech products, this product is suitable for 50Hz, rated voltage is AC660V or 1140V asynchronous motor overload soft start, soft stop and speed control operation, has a wide speed range, speed performance, small starting current, starting torque, smooth starting speed, reliable starting performance, small impact on power and other characteristics. According to the actual conditions choose “S” shaped curve or a straight line starting curve, the curve can be adjusted as needed, thus greatly reducing the impact on equipment start. If on the belt conveyor can reduce the conveyor belt strength requirements, extend belt life and reduce conveyor initial investment. Mine Explosion-proof and Intrinsical Safe Frequency Converter can also be set according to the change of load current automatic adjustment of the motor operating voltage and frequency of power supply, in order to achieve the desired torque, achieve economic operation.
