In light of the third edition

Paul Boughton

Medical device design has undergone a significant evolution over the last three decades. The new IEC 60601-1 standard, first introduced in 1977, now governs the design methodology, verification, safety and risk analysis as well as the implementation of medical electrical equipment.

Now power quality specialist REO UK has updated its REOMED range of medical isolation transformers to bring it into line with changes to the third edition of IEC/EN/UL 60601-1:2005.

The regulatory standard governs the general requirements for basic safety and essential performance of medical electrical equipment. The REOMED range is targeted at patient environments where the rise in the complexity of medical devices has increased mains electrical interference and introduced the risk of electrical shocks and errors in monitoring equipment.

Part of the transition from the second to third edition involved introducing clearer guidance on protection circuitry in relation to AC-DC power conversion, distribution and protection. The new REOMED range uses various means of patient and operator protection (MOPP and MOOP) to meet the stringent requirements related to isolation, impedance, insulation, creepage distances, clearance and leakage currents.

Available in three sizes, the REOMED range of medical transformers has a power rating between 300-1000VA and provides short-circuit and overload protection, all contained in a sturdy metal housing.
