MRI (Magnetic Resonance Imaging) scans provide an invaluable way of obtaining 3D images to diagnose medical conditions. These systems use superconducting magnets operating at around -270°C, usually cooled by liquid helium. Cooling down or warming up a magnet requires a precise process to avoid damage.

A company providing servicing for MRI, CT and PET/CT scanners required 10V, 1000A programmable power supplies. These were to be used for restarting the expensive imaging scanner magnets, providing a gradually increasing current over a 24- to 48-hour time period. Operation from a three-phase 342~528Vac source was necessary.

The GENESYS+™ GBSP10-1000-3P480 model was proposed and accepted for its ability to provide the desired voltages and currents. The product’s compact 2U height and built-in LAN, USB, remote isolated analogue and RS-232/RS-485 interfaces enabled automated control. To avoid accidental adjustment, the blanking front panel option was selected.
