The MilCOTS 3-Phase AC or DC input MPFICQor Isolated Power Factor Correction module is an essential building block of an AC-DC or DC-DC power supply running from a source as defined by MIL-STD-704. It rejects voltage fluctuations from both AC and DC sources and provides Power Factor Correction when operated from an AC source. The MPFIC also rejects pulsed loads, preventing large load transients from being passed back to the AC or DC source. It is designed to comply with a wide range of military standards and is manufactured in the United States.
