50VA single-phase toroidal transformer is designed to step down primary voltage 120V to secondary voltage 30-0-30 volt. Suited for power supply circuitry of electric machines and electronics devices with low nonload losses and weight. The factory possessed the most modern machines, which guaranteed the tightly wound coil and high electrical performance.

Advantages of ATO Toroidal Transformer

  1. High Efficiency: Winding matches the core perfectly, which makes the transformer more efficient.
  2. Long Service Life: With high-quality materials and manufacturing technology, the transformer can be used for 30 years.
  3. Less Noise: The core is seamlessly rolled and the winding is set evenly over it, which makes the transformer quiet when it is working.
  4. Less Radiation: Toroidal structure and winding technology reduce electromagnetic radiation.
  5. Low Temperature Rise: Even if it is overloaded at 120%, the temperature rise will be less than 70℃.

Tips: What is the core material of toroidal transformer?

The core of the toroidal transformer is made of a high-quality cold-rolled silicon steel sheet (generally less than 0.35 mm in thickness) by seamless rolling, which makes its performance of the core superior to that of a traditional laminated core. When winding the coil of the toroidal transformer evenly around the core, the direction of the magnetic lines of force produced by the coil almost coincides with that of the magnetic circuit of the core, and the excitation energy and core loss will be reduced by 25% compared with the laminated core. Made of winding of silicon steel strip, the annular core has a continuous magnetic circuit, while the laminated-core transformer has an air gap between EI sheets. Therefore, the existence of large air gap reluctance is the main shortcoming of laminated-core transformers. By contrast, the annular core has no air gap, and its electrical noise is much lower than that of EI and C-shaped core transformers. On the one hand, the use of vacuum impregnation technology can make the core a solid whole and not deform during winding and processing, on the other hand, the solid annular core reduces vibration and noise.

 
Existing reviews of 50VA Toroidal Transformer, 120V to 24-0-24V/30-0-30V
This is the excellent toroidal transformer I was looking for
I have high requirements for toroidal transformers, no noise, no magnetic leakage, and no noise. Because I have a small space but require enough power, the factories that have bought many toroidal transformers can't send my requirements, either heat or leakage, and ATO's toroidal transformer can meet all my needs.

Whether it has a three-phase autotransformer
Can you provide motorized 3 phase variable autotransformer (variac)
voltage rating: 480V input / 0-560V output.

ATO Responded
Yes. But due to the large capacity of requested transformer (250KVA), our technical dept recommends to modify your request from 3 phase auto transformer into a 3 phase isolating transformer (480V input / 0-560V output), which will be better and more stable.
