Description

дам прикладываетс  отсеченное по фазе и имеющее пик амнлитуды переменное напр жение , обуславливающее предусмотренное управление  ркостью. Общий дл  всех ламп импульсный трансформатор, выполненный только с одной вторичной обмоткой, рассчитан на незначительную мощность, так как он не включен в токовые цепи ламп. Пр ма  подача импульсов высокого напр жени  на катоды ламп всегда обеспечивает одинаковое высокое напр жение на отдельных лампах.The dam is applied a phase-cut and amnlitud peak alternating voltage causing the intended brightness control. A common for all lamps pulse transformer, made with only one secondary winding, is designed for low power, as it is not included in the current circuit of the lamps. The direct supply of high voltage pulses to the cathodes of the lamps always ensures the same high voltage on the individual lamps.
