Доставка 3,5 недели в Кемеровскую область (едут через Казахстан). Заказ, в Москве, перехватила контора PickPoint.
Сначала приехал БП с картинки продавца. Монтаж элементов односторонний, плата залита флюсом (отмываем).
Заказал, через пару недель, приехал другой. Старая версия, с простым межобмоточным конденсатором (не Y типа).
Монтаж элементов двухсторонний. Смотрим его обзор у Kirich (ищем по "24 Вольта 100 Ватт блок питания с неплохим результатом").
Поставил на выход, два фирменных конденсатора 1000uF/35V (13мм) и по входу 100uF/450V (18мм). По питанию ШИМ 47uF/50V.
Место под них есть. Зашунтировал их керамикой. Термистор поставил 5D11 (был 5D9). Установил Y-конденсатор.
Залез в транс - удивился, намотана медь. Обычно китайцы мотают алюминий.
Внимание - на транзисторе (20N60C3) и диодной сборке (B20100G), нет прокладки и нет термопасты.
БП свои параметры выдаёт, претензий нет. Температура элементов (при токе 4А) , примерно как в обзоре у Kirich. За исключением транзистора - у меня получилось меньше.
Всем удачи.
