Chapter 7 Power and Signal Distribution
7.2.1 P OWER SUPPLY ASSEMBLY
These systems feature power supplies with power factor-correction logic. Three power supplies
are used: a 150-watt power supply (USDT unit), a 185-watt power supply (SFF and ST units), and
a 250-watt power sup
th e power supplies.
