shore  frequency converter

 

Dock marine large power variable-frequency power sources is specifically against the wharf, the heat, high humidity, corrosive, or big load of bad impact on the use of environment, special design and manufacture of the muscle power equipment. All PCB circuit boards adopt coating hard-ening;sinusoidal filter,output transformer using the vacuum insulated from maceration paint and protective spray painting, have a higher level and the ability to insulate and full compliance with the classification society ismauditor CCS marine product certification standards.It widely used in the ship,ship building,the garage,the platform and the wharf and needs to change 50hz industrial electricity into 60hz high quality  CVCF Power Source,the vessel with electricity supply of equipment.

BOS shore marine large power inverter modules structure and the advantages:

BOS large power inverter modules contains IGBT ,SMPS,radiator,electrolysis,absorptance
capacitance ,driver board,copper plate etc.the modules adopt IGBT inverter technology,high reliability,small capacity,large making material savings,light in weight,move easily;The match is the best technical Parameters,reducing the wire inductors.In structural design,it get the switch power and the module M57962AL together,can save even more space and bring ability become more strong,it will reduce 50% cost than abroad similar products. It enhance system reliability, and a more evenly distributed, more compact structure, elegant and beautiful.
