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/21496946/bdf-650c-chieftec-proton-series-bdf-650c-modular-80-bronze-650-w 2022-08-21 https://elecena.pl/product/21496946/bdf-650c-chieftec-proton-series-bdf-650c-modular-80-bronze-650-w 2022-12-08 https://elecena.pl/product/21496946/bdf-650c-chieftec-proton-series-bdf-650c-modular-80-bronze-650-w 2025-04-13 https://elecena.pl/product/21496946/bdf-650c-chieftec-proton-series-bdf-650c-modular-80-bronze-650-w 2025-05-06 https://elecena.pl/product/21496946/bdf-650c-chieftec-proton-series-bdf-650c-modular-80-bronze-650-w 2025-06-04 https://elecena.pl/product/21496946/bdf-650c-chieftec-proton-series-bdf-650c-modular-80-bronze-650-w 2025-09-05
