AIF - PFC Power Factor
Correction Series
AIF - PFC 1600W AC-DC Converter Module
The PFC Power Factor Correction module is part of Astec’s family of advanced High Density modular power supply
components. Featuring high reliability and convenient control and monitoring functions, these modules are designed to
reduce product development time and enhance system performance. The PFC is designed to work over all typical line
voltages used worldwide, and provide unity power factor with very low levels of harmonic distortion in line current. The
PFC includes active start-up current control. Power Line Disturbance (PLD) circuitry copes with a wide range of input
voltage fluctuations..
