Power supplies for those computers regulate the 5 V output precisely, and supply the 12 V rail in a specified voltage window depending on the load ratio of both rails. The +12 V supply was used for computer fan motors, disk drive motors and serial interfaces (which also used the −12 V supply).
The advent of switch-mode power supplies has allowed adapters to work from any AC mains supply from 100 to 240 V with an appropriate plug; operation from standard 12 V DC vehicle and aircraft supplies can also be supported.
Zasilacz awaryjny, zasilacz bezprzerwowy, zasilacz UPS (ang. uninterruptible power supply – zasilacz bezprzerwowy) – urządzenie lub system, którego funkcją jest utrzymanie zasilania innych urządzeń elektrycznych lub elektronicznych w przypadku zaniku lub nieprawidłowych parametrów zasilania sieciowego.
ATX12V power supplies are the largest physically, available in the highest wattage ratings, and by far the most common. Full-size desktop systems use ATX12V power supplies, as do most mini-, mid-, and full-tower systems. Figure 16-1 shows an Antec TruePower 2.0 power supply, which is a typical ATX12V unit.
7 cze 2021 · What ATX12VO Is. As the name implies, the ATX12VO standard is essentially about removing the other voltage rails that currently exist in the ATX PSU standard. The idea is that by providing one...
