We at Toroid Technology design and manufacture high quality
Toroidal Transformers for the electronic/electrical industry,
with most of our customers situated inside the European Union.
We are known for fast turn-around with a high level of customer
service, while also maintaining a quality of our transformers
that is second to none.
We offer a wide range of standard Toroidal Transformers and
use in-house developed software to design custom toroids between
15VA and 5kVA to exactly meet your specs.
All of our transformers are CE marked and we have the capability
to make UL-recognized transformers according to UL506 and
UL 601.1 on request.
We also have an IsoBox line of enclosed isolation transformers
for the medical industry with all necessary approvals.
In most applications, Toroidal Transformers are a better,
more efficient choice than conventional laminated transformers.
Some of the advantages are:
weight and smaller size. Typically a toroidal transformer
is about 50% lighter than a corresponding laminated
temperature rise. A toroidal transformer can easily
be designed to a low temperature rise, as the core
losses are very low.
stray field. Well-made toroidal transformers with
evenly wound primaries and
secondaries have a very low stray field important
in f.i. audio equipment and instruments.
mechanical hum. The tape wound core with no loose
ends to rattle is enclosed in the windings. It is
not impregnated with an organic varnish, common in
laminated transformers to subdue noise. This brings
a risk that a laminated transformer starts humming
when the varnish ages and gets brittle.
Mounting. The single bolt mounting mostly used is
simple and straightforward. For increased strength
the center of the transformer can be potted.
prototype adjustment. Because of the whole in the
middle, small adjustments of the secondary voltage
can be achieved by adding turns. Adding them in one
direction will increase the voltage and adding them
in the other directions will reduce the voltage
