• Name: QP series AC crane frequency speed control equipment

        The series QP crane variable-frequency speed regulating electric control equipments can be used matching with master controller (or potentiometer), limit switch, brake, Profibus-DP Fieldbus, remote I/O module and touch screen etc..
        The speed regulating equipment can operate on 50Hz or 60Hz network, and its power supply voltage is within 3×380V-3×660V, controlling the starting, braking, reversing and speed regulating of 2.2kW-2x220kW AC variable frequency asynchronous motor. It can be widely applied in large professional pedestal crane with high speed regulating performance of hoisting, translation mechanism or other material handling system such as metallurgy, installation, port and electric station.
