Power Requirements

Imaging equipment power:

• MRI: 3-phase 400/480V, 100+ kVA service
• CT: 3-phase 480V, 150-200 kVA
• Linac: 3-phase 480V, 200+ kVA
• Fluoro / DR: single-phase or 3-phase, typically under 50 kVA
• C-arm (mobile): single-phase, 20A dedicated circuit

Power quality

Imaging equipment is sensitive to voltage sag / surge. Dedicated transformer + UPS for critical workflows.

Emergency power

Hospital imaging equipment often on emergency generator. Load calcs must include imaging equipment in the generator sizing.
