10V 1000A programmable power supplies used for energising medical imaging magnets

Posted by David on May 24, 2023

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.
