QDC and QDX series marine motor control boxes are used for direct starting, star angle conversion starting and running control of three-phase asynchronous motors of various ships and oil platform equipment, forward or reverse running control, with short circuit, phase loss, overload and loss Pressure protection function. The control box can be set to remote control functions.
QDP series frequency conversion control box is used for frequency conversion start, stop, speed regulation and operation control of three-phase asynchronous motors of various ships and oil platform equipment, with protection functions of short circuit, phase loss, overload and voltage loss. Among them, it is used for fan and pump loads, and its overload force is 120%, and that of heavy load is 170%. Remote control function can be set, and PLC program controller can also be configured to achieve intelligent control of the device. Multiple control boxes can realize single-action, linkage, synchronization and other functions of multiple devices through a centralized control station.
QDR series motor soft start control box is used for soft start control of various three-phase asynchronous motors of marine equipment, which can effectively control the motor starting current within 2.5 times of the rated current, thereby reducing the impact on the power supply of the equipment, and has short circuit, phase loss, Protection functions such as overload and loss of pressure.
QDJ series motor self-coupling buck starting control box is used for self-coupling buck starting control of three-phase asynchronous motors of various marine equipment. By setting and selecting different transformer taps, the motor starting current can be effectively controlled within 1.3 times the rated current In order to reduce the impact on the power supply of the equipment, it also has protection functions such as short circuit, phase loss, overload and voltage loss. The control box can be equipped with remote control functions. By adding some functions such as control, alarm and signal control, it can be used for the control of the ship's lateral thruster motor.
