The PFM4914VB6M48D0CA0 from Vicor is an Isolated AC-DC Converter that steps down an AC input voltage of 85 – 264 V to a DC output voltage of 48 V. This converter delivers an output power of up to 400 W and has an efficiency of 92.5%. It achieves high efficiency with integrated filtering to reduce electromagnetic interference and also includes a self-protecting control architecture to ensure high reliability. This AC-DC converter, when combined with downstream Vicor DC-DC conversion components and regulators, enables the engineer to employ a simple low-profile design without compromising on cost or performance metrics. It also offers a two-sided thermal management strategy that simplifies overall thermal design and allows for efficient heat dissipation.

This converter is available in a chassis-mount package that measures 124.75 x 35.54 x 9.3 mm and is ideal for small cell base stations, telecom switching equipment, LED lighting, and industrial power systems applications.
