DATE: 12-05-2016 VERSION: 1.xx


Переделка блока питания ATX от компьютера на микросхеме TL-494 и её аналогах в регулируемый источник питания с возможностью управлять выходными параметрами: током и напряжением с помощью одного энкодера с кнопкой. От 0,7 Вольт до примерно 24 Вольта (постоянный), Ток от 0,35 А до максимума (13 Ампер и более).

Alteration of the ATX power supply from the computer on the chip, the TL-494 and its counterparts in regulated power supply with the ability to manage output parameters: current and voltage using a single encoder with a button. From 0.7 Volts to about 24 Volts (DC) Current of 0.35 And maximum of 13 Amps or more).
