Relipower provide high quality toroidal transformer 2500VA, it works at 50Hz/ 60Hz low-frequency circuit, with a primary voltage of 120V AC and twin secondary voltage of 2x40V, twin secondary windings may be connected in series or parallel or used independently.

  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℃.
