Recently, A 650W medical power supply has been designed out for open frame for medical field by Artesyn Embedded Technologies with it's output for 12V, 24V, 48V with cooling. 

Such 650W power supply facing the world features a standard 4 x 6in footprint, devices in the CNS650-M range are said to deliver 650W with forced-air cooling (750 W peak) or 400W with convection cooling (650 W peak). No load consumption is said to be less than 500mW.

The supplies can deliver their full output across temperatures ranging from -40 to 50°C and a derated output at temperatures of up to 80°C.

With medical and ITE safety approvals and incorporating 2XMOPP (Means of Patient Protection), the supplies have an input to output isolation voltage of 4000V AC and 1500V AC for input to PE and output to PE. Said to be Type BF ready, the supplies are suitable for powering equipment where there is conductive contact with the patient, such as ultrasound monitors, ECG equipment and operating tables.
