Вообще регуляторов для ЭЛЕКТРОННЫХ БАЛЛАСТОВ не бывает.
Нужно совместимое оборудование - чтобы эл. транс был с возможностью диммирования и диммер был для работы в т.ч. и на электр. транс
Вот Осрамовский транс HTM ,к примеру
Question
Which dimmers can be used for HALOTRONIC transformers?
Answer
Customary dimmers follow either the leading-edge or the trailing-edge phase principle. Depending on the transformer type, either leading-edge or trailing-edge dimmers may be considered for electronic transformers, with one or other of the types of dimmer predominating in the individual countries (e.g. trailing-edge phase control dimmers in Germany).
Dimmers und electronic transformers bear a pictogram consisting of a rectangle containing a ramp and one or more alphabetic characters. Leading-edge phase dimmers for inductive loads bear the letter L , trailing-edge phase dimmers the letter C; the same arrangement of letters is employed for the particular electronic transformers too. It is important for the proper working of the dimmer transformer system that at least one letter in the dimmer and transformer designations tallies, e.g. a transformer HT...L marked C, can be operated with a dimmer marked C.
For trailing-edge phase control dimmers, the corresponding symbol in the pictogram is the letter C
HT 70 L, HT 105 L, HT 150 L, HT 210 L, HT 120 LF
HTM 70, HTM 105, HTM 150
HTN 75
For leading-edge phase control dimmers, the corresponding symbol in the pictogram is the letter L
HTM 70, HTM 105, HTM 150
The HTM series of transformers bears the symbol L and C, meaning that both of the dimmers cited above can be used
