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..

ABSOLUTE MAXIMUM RATINGS
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute
stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of
those given in the operational sections of the specs. Exposure to absolute maximum ratings for extended periods can
adversely affect device reliability.

For AIF04ZPFC-01, total input current for modules connected in parallel must not exceed 16A
For AIF04ZPFC-02, negative rail input rectifiers must be provided by external circuitry. See P.24
Total harmonic distortion – input harmonics meet the requirements of IEC 1000-3-2
