Complete modernization of the popular TESD series with an output power of 10 to 500 W, supplied to support serial consumer production, has been completed.
New opportunities to create additional special functions are made possible by the use of optoelectronic devices with high resistance to ionizing radiation. In addition, it helps eliminate known shortcomings, such as low reliability of implementing isolating transformers in feedback circuits. However, a standard transformer-based feedback design is not excluded.
TESD units are designed in traditional reinforced cases with flanges that allow operation in conditions of strong vibrations and mechanical shocks.
Optimal for use in aplications 1, 2, 3, 4, 6, 11.
