Medical power supplies require special attention to patient safety and isolation. This guide covers key requirements for medical power design.

Patient contact classification determines isolation requirements: Type B (body), Type BF (body floating), and Type CF (cardiac floating) have increasing isolation requirements.

2xMOPP (Means of Patient Protection) isolation is required for patient contact applications. This typically requires 4000VAC isolation and 8mm creepage/clearance.

Leakage current must be minimized for patient safety. Medical power supplies typically require <100μA earth leakage and <10μA patient leakage.

Risk management per ISO 14971 is required for medical devices. Power supply failure modes must be analyzed and mitigated.
