Product introduction: Goodrive300-39 is a special inverter with integrated control specially developed for the load characteristics and control requirements of construction hoists. It integrates the electrical logic, frequency conversion control, brake power supply, and overload protection functions of the construction hoist, and adds the functions of text display, voice broadcast, floor call, automatic leveling, and GPRS/GPS remote monitoring, which can meet the medium and high-end application needs of energy-saving and low-speed construction hoists.
