S11 series transformer is one kind of low loss copper winding product. It adopts high quality material, especially applying the new technology and new material to the insulation of the coil and transformer body, thus the no-load and the load loss are obviously reduced, the performance and structure are more reliable and superior

PRODUCT ADVANTAGE

Transformer shell can withstand hightemperature, good overload ability,impact resistance and insulation.
High quality terminal, with wiringinstructions, easy to install.
Pure copper material Enhance mechanical properties,mechanical strength, dynamic stabilityand thermal stability.
Heat Sink Reasonable arrangement of heat sink,can dissipate heat faster.
Oil level gauge Red means low oil level, blue meansnormal,oil level is clearly visible
