PFC has no effect on the operation of the motor itself.

- power line networking
Power line networking uses power line communications (PLC) to connect computers using existing power outlets in the home, essentially transforming every electrical outlet in the building into a network connection. Power line networking is one of the cheapest forms of home networking and has a low start-up cost and minimal IT workload. And despite using […]
- power management
Efficiently directing power to different components of a system. Power management is especially important for portable devices that rely on battery power. By reducing power to components that aren’t being used, a good power management system can double or triple the lifetime of a battery.
- power-on self test
Abbreviated POST, a diagnostic testing sequence run by a computer��s BIOS as the computer��s power is initially turned on. The POST will determine if the computer��s RAM, disk drives, peripheral devices and other hardware components are properly working. If the diagnostic determines that everything is in working order, the computer will continue to boot.
