It is applied to the centralized photovoltaic inverter, connected to the output of PV inverter and the grid side, and plays the role of voltage transformer and electrical isolation.
According to the demand of grid connection, it can be made into an ordinay double winding isolation transformer, and can also be made into an input double split structure. It plays the role of voltage variation and electrical isolation.
It plays the role of voltage variation and electrical isolation. According to the demand of grid connection, it can be made into an ordinary double winding isolation transformer, and can also be made into an input double split structure.
The coil is made of European winding technology and vacuum impregnation. The product has compact structure, low running noise and high mechanical strength. The dual split transformer adopts an axial split structure, which can effectively suppress the unbalanced current.
