Power Factor is typically expressed as a percentage of Unity (1.00). The average switch mode power supply has a power factor of 0.60 or 60%. This means your device is throwing away up to 40% of the power it gets, effectively sending it back to the power company. Switch Mode Power Supplies (SMPS) have a typically poor Power Factor because they "gulp" a small portion of the AC sine wave, wasting the rest. Power factor is "corrected" when more of the wave is used to provide the power that an SMPS requires.

Leveler product offerings conserve the energy demanded by electronic systems by 15% - 30%, improving the power factor and reducing the amount of energy demanded during the operation of electronic equipment. Generally, there is a complementary reduction in Harmonics associated with improved Power Factor.

Leveler Technology performs Power Factor Correction, the process of bringing Real Power used to equal Apparent Power. On average, Leveler corrects power factor by 30%, bringing a 0.60 power factor device into the 0.80+ range. This equates to less power sent back to the power company, and more power available in your electrical circuits.
