Product Structure

Performance

1) The structure is compact and reasonable, and the volume is small, which is only about one-third of the European-style box change of the same capacity;
2) Fully sealed, fully insulated structure, no need to set up safety barriers, and reliable guarantee for personal safety;
3) There are a variety of power supply schemes for users to choose from, which can adopt terminal power supply and realize ring network or dual power supply;
4) S11 oil-immersed power transformer is adopted, which has low loss, low temperature rise and strong overload capacity;
5) Double fuses (backup protection fuse + plug-in fuse) are used for protection, and the plug-in fuse fuse has the current and temperature dual sensitivity characteristics to ensure the safe and reliable operation of the product;
