Description
[html]Для подключения низковольтной нагрузки при доступности сетевого напряжения 220 Вольт, традиционно используются блоки питания. Такие источники все чаще выполняются по импульсной схеме, выгодной отличающейся от трансформаторной: малым весом и габаритами; достаточной мощностью.Среди импульсных блоков питания, самые легкие, компактные и доступные по цене – это сетевые адаптары, отличающиеся широкой линейкой выходных напряжений. Такие устройства выпускаются в пластиковом корпусе и рассчитаны на относительно небольшие токи в пределах нескольких ампер, что вполне достаточно для питания многих электронных схем.К недостаткам вилочных блоков питания можно отнести герметично закрытый корпус, что ухудшает отвод тепла, особенно при эксплуатации на максимальном токе нагрузки. В таких случаях лучше купить блок питания большей мощности.Подобный источник стабильного постоянного напряжения характеризуется низким коэффициентом пульсации и незначительным уровнем помех.Сфера применения:Такой источник питания может использоваться для подключения всех видов нагрузки. Это могут быть радиолюбительские схемы, детские игрушки, устройства автоматики.Учитывая растущую популярность светодиодного освещения, блок питания может использоваться для питания светодиодной ленты или модуля.[/html]
