Why to use the“Amorphous Transformer“

There are two kinds of loos of transformer : one is un-loaded loas and the other one is loaded loss. The first one is two time greater than the latter one. By using Amorphous Alloy as core material ca nsignificatnly reduce the un-loaded loss. The follow is the coparison chart for your reference.
