SMALL SIZE Most toroids are smaller than their E-I transformer counterparts. Electrical and mechanical designers appreciate a toroid’s compact dimensions. They are particularly well suited where low height is a consideration.
|
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.
|
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 MECHANICAL HUM The core of a toroid is formed from a single strip of grainoriented 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 isthe flexibility to vary dimensions. Because ECKO 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.
|
LOW WEIGHT Because they are more efficient, toroids can be up to 50% lighter, (depending on power rating), than conventional laminated transformer. Low weight simplifies end product design by reducing mounting hardware and supporting enclosure requirements.

LOW NO-LOAD LOSSES
Compared to conventional E-I transformer, 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%.
|
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 associated with conventional E-I-laminated transformers... and three screws are eliminated at assembly!
