FPM500F - 450-500 WATT Single Output MEDICAL CLASS II POWER SUPPLIES

Medical Open Frame

The FPM500F series of AC-DC medical approved switching power supplies in a package of 3.98 x 7.09 x 1.56 inches are capable of delivering 450-500 watts of continuous power at 30 CFM forced air cooling or 250 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.
