Data Sheet for MW75S AC-DC Power Converter - .PDF file.

Martek Power has announced the release of the MW75S 75W AC-DC front-end power supply, which is claimed to meet the most rigorous specifications for military and commercial-aviation applications.

The MW75S is part of the MW Series product line, which features active power factor correction (PFC) and offers aircraft electrical-system designers plug-and-play power solutions.

A key feature of the MW75S is active power factor correction, which improves the efficiency of an electrical system by reducing harmonic content and/or aligning the phase angle of incoming current so that it is in phase with the line voltage.
