Over 95% of our sales is custom designs. Because they require no elaborate production tools and are individually wound, toroidal transformers are particularly suited to custom designs.

Take advantage of our custom design service at no obligation.

Custom designed toroids are our specialty:

  • Computer aided programs provide quick solutions and optimal designs from AC or DC load data
  • Rapid delivery of prototypes
  • Variety of mounting arrangements
  • Pre-certified by electrical safety agencies: UL and CSA
  • Quick response to RFQs
  • Lifetime Warranty
