ATO step up/step down toroidal power transformers meet modern-day requirements for small size and lightweight. The power capacity range from 50VA to 5kVA, all copper wire design, has numerous approvals covering a wide variety of international standards. It features a single primary voltage of 110V/120V/220V/230V/240V AC 50/60Hz and a single or double secondary voltage like 12V/24V/2x24. The toroidal shape gives a significantly higher efficiency compared to conventional transformers of the same size. Our standard safety toroidal transformers can be ordered easily and are customizable.

Among the toroidal transformer products, there are many well-known products in audio equipment. Such as high-performance products that can be used as power transformers in high-power hi-fi amplifiers and power transformers for medium and small power audio equipment.
It can be used in current and voltage transformers. New high-performance magnetic materials such as permalloy soft magnetic materials, amorphous materials or nanocrystalline alloys can be used as magnetic cores, with precise intelligent instruments and special testing methods. It can ensure accurate transformer parameters and completely consistent performance.
Toroidal transformers are specially designed and manufactured for medical equipment. In addition to high efficiency, high reliability and high safety requirements, it also especially strengthens the electrical strength and improves the anti-humid heat performance. A thermal fuse is also required to be added inside the transformer to ensure reliability.
Compared with ordinary transformers, toroidal transformers have great advantages in efficiency, temperature rise, cost, anti-interference, and longevity. ATO toroidal transformer specifications are: 50VA, 70VA, 120VA, 150VA, 200VA, 500VA, 1000VA, 3000VA, input voltage: 110V, 120V, 220V, 240V, output voltage: 12V, 24V, 110V, 120V, etc. For a more detailed toroidal transformer use case video introduction please see:
