Регулируется от 9.5В до 24.3В, на холостом ходу показания отличаются на 0.1В от мультиметра, что довольно неплохо. 3А на 24В выдает, правда напряжение при этом просаживается на 0.7В, что терпимо. Регулировка довольно грубая, что усуглубляется тем, что потенциометр вращается приблизительно на 250 градусов а регулирование осуществляется только в диапазоне 0-170 градусов, а далее напряжение достигает максимума и уже не меняется. Так что выставить напряжение с точностью до 0.1В будет проблематично, да и особо не надо для такого блока питания. К недостаткам могу ещё отнести то, что данный блок питания потребляет на холостом ходу при 24В около 3Вт ( при 9.5 - около 1Вт). Хорошие блоки питания для ноутбуков на холостом ходу вообще ничего не потребляют (менее 0.1Вт).
