1И18/20**-А-01-017-УХЛ4* Ватра 01 93
Первый нормальный дроссель для 18(20)Вт ламп у меня :). Судя по распространенности 40Вт ПРА такой же конструкции: http://fotkidepo.ru/?id=photo:895441 18Вт вариант был гораздо менее распространенным :(. Ибо насколько помню - ранее таких ПРА ни в галерее, ни в инете вовсе не видел. R(DC) обмотки - 28,8Ω (при разогреве до сильно теплого, но еще не горячего сопротивление обмотки повышается до 31,2Ω), tw=130ºC, Сosφ=0,35. Проверял дроссель с французской лампой Philips 18W/840. В итоге при напряжении 220В ток лампы (прогретой до теплого ранее) составил 0,37А. Замерил также и ток подогрева при том же напряжении - 0,43А. Данный дроссель установлен с светильнике ЛПО 16-18 / Н-08 УХЛ4: http://fotkidepo.ru/?id=photo:1093974.
