TH8 - 220 - 400
Food transformers small - sized low - voltage filament TH8 - 220 - 400 are intended for food of filament chains of the radio - electronic equipment of industrial function assembled on electrovacuum and semiconductor devices with tension of network of 220 V and with a frequency of 400 Hz.
Filament TN transformers depending on the dimensional power, type of a magnetic conductor, tension of network of food and climatic modification have various overall and adjusting dimensions. The design of transformers is developed for installation on the metal chassis of the equipment or on printed circuit boards with fastening by their screws.
Provide with consecutive or parallel connection of windings various combinations of currents and tension.
Are made in vseklimatichesky execution and for operation in areas with the moderate frigid climate in accordance with GOST B 20.39.404 - 81.
