FPM450 - 450-480 Watt Medical Triple Output Power Supplies

Medical Open Frame

The FPM450 series comprising single and multiple output models for 450-480 watts of continuous output power is specially designed for medical applications. They operate at 90-264 VAC input voltage without the need of a selector strap. 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.
