Ramping changes the current in a superconducting MRI magnet during planned installation, deinstallation, or service. The power supply is one part of that work: system compatibility, magnet condition, cooling support, and the approved service procedure also matter.

Start with the Magnet and Service Scope

A power supply should be selected for the specific magnet and task—not simply for its brand name or portability. Qualified engineers must confirm the applicable electrical requirements, cables, interfaces, documentation, and service conditions before work begins. Compatibility with selected systems from several manufacturers does not mean compatibility with every magnet from those manufacturers.

Automation Supports the Engineer

Automated ramp profiles can support a consistent workflow, but they do not remove the need for trained oversight or manufacturer instructions. Ramping can involve helium loss and quench risk. Automation does not make a procedure error-proof. Helium use and completion time depend on the magnet, its condition, and the service plan.

What the MPS2 Offers

The Digit Systems MPS2 Universal Ramp Shim Power Supply combines a compact design, auto-ramp capability, and support for compatible GE, Siemens, and Philips systems. Its four-quadrant operation supports controlled current and voltage handling during applicable ramping tasks.

The MPS2 also supports active shimming on compatible GE LCC magnets. That capability is distinct from ramping and from routine patient-specific scanner shimming; each requires the appropriate system configuration and procedure.

Plan the Job Before Selecting the Tool

Share the magnet model and intended service scope with Digit Systems so the team can review compatibility and the required setup. A suitable tool supports the service plan—it does not replace it.

Contact Digit Systems to review MPS2 compatibility and the equipment needed for your project.
