PS-2142-1D - Zasilacz impulsowy dużej mocy - podniesienie napięcia

Witam Zwracam się z prośbą do szanownego grona forumowiczów, mam zasilacz impulsowy Lite-On PS-2142-1D, daje na wyjściu 12V max. 121A oraz 3,3V max. 5A. Zasilacz ma zabezpieczenia Over Voltage, Under Voltage, Over Current Chciałbym zwiększyć napięcie wyjściowe z 12V do 14,2V (+/- 0,2V). Wyjście 3,3V nie będzie używane. Wiem, że można zrobić np. włączając w szereg diodę razem z diodą Zenera albo zmieniając dzielnik napięcia. Niestety stopień skomplikowania zasilacza powoduje, że nie wiem, o którą diodę Zenera / dzielnik napięcia chodzi. Schemat w załączniku (Adobe Reader może wymagać dociągnięcia fontów, potem już otwiera się poprawnie). Z góry dziękuję za pomoc typer
