Custom Designed Toroidal Power Transformers
When our family of standard design transformers does not suit your application, we are happy to design a custom toroidal transformer to your exact specifications. From 15 VA up to 75 kVA single phase or 225 kVA three-phase for 60 Hz frequency. For 50/60Hz, we can design custom toroidal transformers up to 60 kVA single phase or 180 kVA for three-phase configuration.To design a transformer with optimum performance and the lowest possible price, we should know your application and the duty cycle of the transformer. The most cost effective design uses a core with a diameter to height ratio of 2:1.
See our Design Guide for more details.
In addition to our regular toroidal cores, you can also specify the low profile O-Cores (up to 2,000VA). The O-core has a round cross section that offers an even lower profile than our regular toroidal core with a square cross section.
