Over 95% of our sales are custom designs. Because they require no elab-
orate production tools and are individually wound, toroidal transformers
are particularly well suited to custom designs.
Take advantage of our custom design service at no obligation.
Our interactive computer design capabilities enable us to optimize
design’s for either AC or DC loads.
