Toroidal transformer input could be provide with single ,double or triple voltage winding,output can be provide from single to several winding.The capacity from 20VA to 25000VA,With their high efficiency , smaller in size, lower in weight, less mechanical hum ,low exterior magnetic field, low off load losses without size limit and single mounting point ,our toroidal transformers are widely applied to audio equipment,medical equipment,stage light ,medical equipment,etc
