650W ac-dc power supplies deliver class-leading density

MURATA POWER SOLUTIONS PQU650 series of open-frame, 650W-rated ac-dc power supplies provide high power-density, with forced air- and convection-cooled ambient ratings. Units deliver a multitude of standard features including wide output voltage adjustment range, auxiliary power rails and a high transient capability at a competitive price. Measuring 6″ x 4″ by 1.75” (1 U), product accept a universal ac input voltage range of 90Vac to 264Vac. Utilizing the latest LLC topology results in world-class efficiency levels of up to 95%, product series maintains a high 450W convection-cooled rating. This means there are no system fan requirements for applications up to 450 W at ambient temperatures as high as 50°C, and with as little as 300 LFM forced air-cooling, the available output power rises to 650W at an ambient temperature of 50°C.
