VTC407497 The VTC407497 is a high-performance AC-DC converter providing all the necessary functions for a distributed power system front end. Built-in power factor correction virtually eliminates unwanted AC harmonic currents, delivering over 50% more power from standard outlets while also meeting the international harmonic current limits. Universal AC input allows worldwide operation without jumper selection or auto-ranging. A simple control interface provides required system functions: front panel on/off switching, AC fail warning, a low-voltage auxiliary supply and enabling the distributed DC-DC converters. Its many features, small size, and low cost make the VTC407497 the right choice for OEM applications.
