A medical-grade toroidal transformer is an electrical isolation device specifically designed for use in patient-connected medical equipment. These transformers are built to meet strict safety and regulatory standards, such as UL 60601-1 and IEC 60601-1, which govern leakage current, insulation, and reliability. Their toroidal (doughnut-shaped) core minimizes electromagnetic interference (EMI) and audible noise, key considerations in hospital and clinical environments.
