In the active PFC power, I saw two parameters: bronze and white,
Bronze requirements are 82,%, 85%, 82%., in general, bronze power supplies better than white card power supply
Bronze medals and white cards are two levels of 80plus certification,.80plus certification is the conversion efficiency of the power rating, the power conversion efficiency is higher, the more power-saving, so this certification is now very popular
80plus certification is divided into: white cards, bronze medals, silver medals, gold medals, white gold medals, titanium medals, grades ranging from low to high. White cards require power at 20%, 50%, 100%, three loads, conversion efficiency is higher than 80%,
