Toroidal transfomers
TT Type
Toroidal transformers from the TT series are developed for building into power supply circuitry of electronic devices, audio devices, medical electrical equipment and low-voltage lighting systems, featuring low no-load losses, small dimensions and weight and low stray magnetic fields. The transformers are made with Class II insulation and maximum ambient temperature 40 degrees Celsius.
