To compare with the traditional EI Transformer, the Toroidal Transformer has the advantages are small size, leakage magnetic is samll, high efficency, internal resistance is samll and fast raction.
1.
Application:
Electronic meter and apparatus
Cable TV and digital network
Electronic control
Medical equipment
New electric power supply
Decorative illumination system
