Muxa52 VIP2RU23/10/2019Блок питания доехал до Москвы примерно за 2 недели. Доставка до двери. Полностью работающий. Из особенностей отмечу многооборотный резистор установки напряжения. Резистор установки ограничения по току к сожалению простой. В схеме имеются 2 терморезистора, которые контролируют температуру ключей и выходного сдвоенного диода. Интересно, что параллельно выходу установлен 5А обратный диод защиты блока питания при их последовательном включении. Диод защищает выходные конденсаторы от переполюсовки когда блок питания работает в группе последовательно включённых блоков, а сам выключен, когда другие включены. В общем хороший блок питания и сделан добротно.

Works as expected. Switching frequency is roughly 150kHz, noise cca 5mV, ripple up to 50mV (visible on picture).Fan does not run, until it gets hot...
