Home medical devices can provide an excellent first line of defense when dealing with health and medical issues, and there is an increased need for at-home care for patients released from hospitals and other healthcare facilities.

The medical technologies used in nonclinical environments range in complexity from simple materials for administering first aid to sophisticated devices for delivering advanced treatment.

Complex at-home electrical medical devices must comply with the stringent IEC 60601-1 safety standards for medical patient protection. They must also adhere to additional requirem…

EMC requirements for medical power supplies

A look at IEC 60601-1-2 4th edition requirements

By Ron Stull, Power product marketing engineer

While the original IEC 60601-1 standard has existed now for 40 years, technology has evolved and the environments where medical equipment is used has grown more complex. This has led to the consideration of risks due to electromagnetic interference and a collateral standard on electromagnetic compatibility.

In the following post we will take a look at IEC 60601-1-2 4th edition EMC collateral standard, how it relates to medical power supplies, and its effective date in each region.

IEC 60601-1-2 4th edition requirements

The underlying premise of IEC 60601-1 is understanding and managing risk, which the 3rd edition developed by defining electrical performance requirements for safe operation in terms of the means of protection for both patients and operators. Principally this determined isolation, creepage and insulation specifications for differen…
