THE ADVANTAGES AND BENEFITS OF USING AMVECO TOROIDAL TRANSFORMERS
On this page you can learn about the advantages and benefits of using our toroidal
transformers. First we would like to list four features that are unique to AMVECO and
its line of toroidal transformers. Four features that you will surely benefit from.
• AMVECO is an ISO 9001 registered company
• AMVECO’s transformers use only flameretardent material (UL 94-V2)
• AMVECO offers lifetime warranty for its products
• AMVECO’s transformers are recognized to several UL standards and
certified by CSA as well as TUV for medical applications.
High Performance Products For Your High Performance Applications.
SMALL SIZE
Most toroids are smaller than their E-I transformer counter-
parts. Electrical and mechanical designers appreciate a
toroid’s compact dimensions. They are particularly well suited where
low height is a consideration.
LOW WEIGHT
Because they are more efficient, toroids can be up to 50%
lighter, (depending on power rating), than conventional lami-
nated transformers. Low weight simplifies end product design by reduc-
ing mounting hardware and supporting enclosure requirements.
LOW STRAY MAGNETIC FIELD
Toroids have no airgaps: primaries and secondaries are wound
uniformly around the entire core. As a result, toroids emit very
low radiated magnetic fields. This makes the toroid ideal for applications
involving high sensitivity circuitry.
LOW NO-LOAD LOSSES
Compared to conventional E-I transformers, toroids exhibit
extremely low no-load losses. In applications where a circuit is
in a “stand-by” mode for long periods, the potential cost reduction for
power can be significant, sometimes 80-90% lower.
LOW MECHANICAL HUM
The core of a toroid is formed from a single strip of grain-ori-
ented electrical grade silicon steel tightly wound in the form
of a clock spring with the ends spot-welded in place. The copper
wire is wound over polyester film, forming a silent, stable unit without
the use of environmentally unfriendly glues or varnishes.
FLEXIBLE DIMENSIONS
Compounding the benefits of low weight and small size is the
flexibility to vary dimensions. Because AMVECO is not tied
down to core caps or lamination sizes, the height and diameter
of our toroids may be economically varied to accommodate equipment
design requirements.
HIGH EFFICIENCY
Due to its unique construction, toroids are typically between
15 and 30% more efficient than the conventional type. As a
rule; the larger the transformer - the more efficient it becomes.
LOW OPERATING TEMPERATURE
Since most of the losses in a toroid are in the copperwire, the
toroid cools off quicker than the conventional E-I type with
more iron. At half the load, the toroid’s temperature rise is only
about 30% of what it is at full load.
EASY TO MOUNT
A single center screw easily and quickly mounts the toroid,
avoiding costly mechanical design and practical problems associ-
ated with conventional E-I-laminated transformers..., and three screws are
eliminated at assembly!
