With the current PROTON series, CHIEFTEC has branched out into new Double Forward technology. The basis for this is special, high-quality capacitors. These Double Forward switching power supplies use these capacitors to achieve the best possible efficiency. The advantages are obvious: they save energy and offer much higher efficiency and solid performance, which in turn ensures a longer service life of the installed components. PROTON power supply units are 80PLUS BRONZE certified to meet all ENERGY STAR 5.0 and higher standards. https://elecena.pl/product/21496944/bdf-850c-chieftec-proton-series-bdf-850c-modular-80-bronze-850-w 2022-08-21 https://elecena.pl/product/21496944/bdf-850c-chieftec-proton-series-bdf-850c-modular-80-bronze-850-w 2023-08-28
