    понижающий преобразователь
    хороший преобразователь, мощный, 150W нагружал, а он даже не вспотел)) в общем всё как написано. одну звезду снял за плохую упаковку, заказывал вместе с паяльником, прислали всё в галимом пакетике и стандартном пупырчатой конверте. паяльнику ничего, а у преобразователя радиатор был погнут и уголок самой платы загнут. к счастью всё работает.
