With main components of imported high quality frequency transducer, contactors, circuit breakers, leadingin reactors, filters, PLC programmable controller or industrial personal computer and other equipment, design and manufacture of three-phase AC motor starting, speed regulating , protection, control and monitoring systems. Marine inverter control system combines the most advanced technology and control functions, it can meet the application requirements of most of today’s Marine Electric Drive, such as: lifting, transportation, lifting,ventilation, air conditioning, pumping, compression machinery, special machinery and so on, especially suitablefor application systems with high requirements for the motor speed regulating, steady speed, torque adjustment,constant torque, constant tension, etc.
The control mode of the Inverter is pulse-width modulation, so as to drive the motor. The pulse-width modulation provides adjustable current to the stator, so as to achieve excellent speed control results. At this time, the motor can be regarded as a speed source, whose speed is only decided by the input frequency of the stator, so ad to realize acceleration and deceleration speed adjustment. It has a very wide speed range and can compensate the resistance slow down.
Depending on the application requirements, it can be equipped with PLC programmable controller or IPC PLC adopts free communications with RS485 interface, so as to realize intelligent ditital control of inverters.
Inverter gains excellent control characteristics from space vector estimation and optimized inverter trigger pulse mode for decreasing motor loss and switch loss. It has powerful computing features and rapid response capability., good dynamic performance, high power factor, low harmonic content and good speed governing performance.
