Applications:  
    Shore Power supply, that is, shore power supply with frequency conversion, also known as electronic static shore power supply. It is specifically designed and manufactured to be high-power frequency conversion power supply for boat, shore pier and other harsh environments such as high-temperature, high-humidity, high-corrosion, and heavy load shocks. It is widely used in boat, ship manufacturing and repairing plant, offshore drilling platforms, shore piers and other power supply situation where 50Hz industry electricity should be switched to be 60Hz high quality CVCF power supply for electrical equipment of the ship.
 
Features:
    Shore Power supply is higher than the average standard variable frequency power supply, the core inverter module is mainly connected to each other by IGBT (insulated gate bipolar transistor), switching power supply, radiator, electrolysis, absorption capacitor, drive board, copper board and other components. The module group applies IGBT inverter technology to be high reliability, small size, significant savings in manufacturing material, light weight, and easy to move. Furthermore, it can automatically match the best technical parameters, and reduce the wiring inductance. The system reliability is enhanced, but also capacitance is distributed more evenly, and structure is more compact, simple, and elegant.
