QDP series marine motor control box is used for variable-frequency starting, stopping, speed regulation and operation control of three-phase asynchronous motors of various ship equipment, and has the protection functions of short circuit, phase loss, overload and voltage loss.
The control box is applicable to 380v/50hz, 440v/60hz or other electrical systems. For fan and pump loads, the overload force is 120%, and the overload force of heavy load is 170%. The remote control function can be set, and the PLC program controller can also be configured to realize the intelligent control of the equipment. Multiple control boxes can realize single action, linkage, synchronization and other functions of multiple devices through the centralized control console.
● applicable environment:
Ambient temperature: -25 ℃ - 45 ℃
Tilt and swing: ± 22.5 degrees
Impact, vibration, salt fog, mold and humid air on the sea caused by the normal operation of the ship
The protection grade of the box is IP22, and it can also be made into IP44 or IP56 according to user requirements.
● basic specification of QDP series motor control box and matching and type selection of motor:
For fan pump type, the model of frequency conversion cabinet corresponds to the power of light load frequency converter, and the power selection of motor can correspond to the model of frequency conversion cabinet, or it can be reduced by one specification, without power distribution resistance cabinet.
For the heavy-duty type, the model of the frequency conversion cabinet corresponds to the power of the heavy-duty frequency converter, and the power selection of the motor can correspond to the model of the frequency conversion cabinet, or the power distribution resistance cabinet can be reduced by one specification.
