Power Factor Correction Technologies
Indicated for systems with high, continuous inductive
load, for power savings and extended motor life.
Overview
"Most power factor units draw energy continuously, making up for savings unless the home has an unusually large inductive load, e.g. pool pump, old refrigerator or AC. Newer appliances have
power factor correction built in. Most homes will not save money by the time the
unit ROI and continuous energy draw are factored in." -- Sterling
D. Allan (Oct. 2, 2007)
"It is important to realize that billed energy is a
function of amps x watts x power factor. So when talking about power
factor increasing and amps dropping, be sure that the final tally is better
than the original, by enough to make purchase of the unit worth while." -- Sterling
