Zasilacze Astec AA21660 mo\u017cna przerobi\u0107 na zasilacz daj\u0105cy\u00a0 13.8V \/ 24A.<\/p>\n

Fabrycznie daj\u0105 one 24A dla napi\u0119cia 12V i 27A dla napi\u0119cia 5V, przy mocy ci\u0105g\u0142ej 400W. Takie zasilacze s\u0105 u\u017cywane w r\u00f3\u017cnych systemach storage firmy Engenio (dawny LSI Logic), kt\u00f3re s\u0105 OEM-owane przez r\u00f3\u017ane firmy np. IBM (linia TotalStorage DS4xxx i DS5xxx), NetApp i inne. Numer FRU IBM to\u00a0 19K128.<\/span><\/p>\n

Je\u015bli zosta\u0142 u\u017cyty potencjometr, to ustaw go tak aby uzyska\u0107 napi\u0119cie wyj\u015bciowe 13.8V.<\/p>\n

Zasilacz do pracy ci\u0105g\u0142ej z du\u017cym obci\u0105zeniem wymaga wymuszonego obiegu powietrza. Je\u015bli jest to konieczne, to zainstaluj dodatkowy wiatrak.<\/p>\n
