OEM
With the uncertainty in global trade patterns, and recognition of the need for local and reliable manufacturing, Torus Power is now opening its toroidal transformer design and manufacturing facilities for OEM applications.
Founded in the 1980s, Torus Power and its predecessor company Plitron Manufacturing have been a respected and reliable OEM supplier to many of the world’s leading companies in audio, video, medical and other industries.
Torus Power brings decades of experience in toroidal transformer design and manufacturing. Torus Power is the best choice to supply premium quality toroidal transformers to discerning OEMS where performance and quality are paramount.
Advantages of Toroidal Transformers
High Efficiency
Lower core losses: Toroidal cores are made of continuous grain-oriented silicon steel or ferrite, with fewer air gaps, reducing energy lost as heat. Less power wasted: Higher efficiency (typically 90-95%) compared to EI transformers.
Compact Size & Lightweight
Better power-to-weight ratio: You get the same power output with a smaller and lighter transformer, which is great for tight spaces.
Low Electromagnetic Interference (EMI)
The closed-loop core design means less. stray magnetic field, reducing interference with nearby sensitive electronics.
Quiet Operation
Due to the uniform magnetic field and low vibration, toroidal transformers are quieter — they produce less hum compared to laminated core types.
Better Voltage Regulation
They respond quickly to load changes, maintaining more stable voltage outputs under varying load conditions.
Reduced Mechanical Noise
The continuous core and tight winding reduce magnetostriction and noise from mechanical vibrations.
Customizable Design
Easier to wind custom voltages or add multiple secondary windings, especially in audio, medical, or custom electronics.
