Custom Designed Toroidal Power Transformers
our family of standard design transformers does not suit your application,
we are happy to design a custom toroidal
transformer to your exact specifications
up to 32,000 VA single phase or 96,000 VA three-phase for 60 Hz. For
50/60Hz, we can design custom toroidal transformers up to 32,000 VA single
phase or 96,000 VA for three-phase.
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.

In addition to our regular toroidal cores, you can also specify
the low profile O-Cores (up to 2,000VA)
which offer an even lower profile.
A metal washer and rubber pads provide the most economical way of mounting
the transformer horizontally and is adequate for transformers under 600 VA,
provided the transformer is not installed in a product that receives rough
handling. Above 600 VA, epoxy potted center is standard mounting method.
Prices include mounting hardware, either a
steel washer and two rubber pads or as
shown for larger sizes, an epoxy potted center with one or two drilled
Optional Potted Center
For a nominal cost you can order smaller transformers with epoxy
potting, either with drilled hole
or threaded inserts. The potting has a recessed top to accommodate screw
head. Flat bottom is standard feature.
An L-shaped steel bracket is an economical solution for vertical mounting. A
metal washer and two rubber pads are furnished with each L-bracket.
