One of the key safety concerns with respect to medical devices is, that the patient is often electrically connected to the medical device. Since a medical device must be absolutely safe for both, the patient and the operator, all electronics including components must meet strict requirements according to IEC/EN 60601-1.

As an example: AC/DC power supplies and DC/DC converters for medical and healthcare applications, need to fulfill much stricter requirements compared to power supplies for the industrial market. Some of them main technical differences are additional requirements on the isolation system (2xMOPP), the leakage current, the isolation capacitance and EMC limits.

Traco Power offers both AC/DC and DC/DC solutions for medical applications, all of which fulfil the 2xMOPP requirement. Compliant with EMC requirements of the 4th edition of IEC/EN 60601-1, they are suitable for all patient connected, body floating rated applied parts medical devices.

The AC/DC products range from small 5W PCB-mounting modules, a range of mid-power open frame designs, and enclosed power supplies offering power levels of up to 850W.
