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 RDDLZ 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.
