Transformers type TN

Unified power transformers type TN (filament transformers) - a type of power transformers used in electronic equipment, they, like TA and TAN transformers, are connected to an alternating current network with a frequency of 50 Hz and a voltage of 127V or 220V since it was assumed that they would be used for filament circuits of radio tubes, the secondary windings of these transformers provide voltages only 6.3 / 5V. However, the presence of several secondary windings expands the possibilities and their use. The main technical parameters of VT transformers are given in the tables:
