Power Factor Correction (PFC)

Power Factor Correction is an active rectifier, that draws a sinusoidal current from the line. New laws and restrictions are in effect since 1992, requiring active power factor control on all power supplies above 200VA. Conventional Rectifiers draw pulsed currents from line resulting in many disadvantages and problems: creation of harmonics and RF. high losses, require overdimensioning of parts. reduced max. power, that can be drawn from line.

Topower's Power Supply has the High Level PFC Value at 0.95~0.989 which has best energy Saving
