Murata announces the PQU650 series of open-frame, 650 W-rated AC-DC power supplies by Murata Power Solutions. The PQU650 series offers the highest power-density product on the market, with forced-air- and convection-cooled ambient ratings. The power supplies offer a multitude of standard features including wide output voltage adjustment range, auxiliary power rails, and a high transient capability at a competitive price.
The high power density product, allows for no fan applications up to 70c amb (with derating), and the compact size makes them ideal for applications with size constraints. Optional connections are provided for a wide variety of applications and the PSU provides high power for short durations.
Applications include: industrial, medical, communications, test equipment, visual signage, broadcast, STE, stage lighting, PoE, and data communications
