450-500 Watt Single Output Medical Power Supplies : FPM500

FPM500 - 450-500 Watt Single Output Medical Power Supplies


Medical Open Frame

The FPM500 series of AC-DC medical approved switching power supplies in a package of 4 x 7 x 1.7 inches are capable of delivering 450-500 watts of continuous power at 30 CFM forced air cooling or 350-400 watts at convection cooling. The units are constructed on a printed circuit board with a U-bracket for mechanical support and heat sinking. A cover and fan assembly can be added during manufacturing. They are designed for medical applications including those needing BF rated insulation and/or an operation altitude up to 5000 meters.
