New Medical Isolation Transformers Comply With EN 60601-1 Third Edition

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.
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.
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.
"The UK and Europe are leading the way when it comes to regulated development of electrical medical devices," explained Steve Hughes, managing director of REO UK. "The third edition is suited to the rising complexity of modern medical setups. Devices including tablets, smartphones and personal computers disrupt the mains voltage network, which can affect the sensitivity of diagnostics and monitoring equipment.
"Our new REOMED range has been developed for use in patient and medical environments and provides safe galvanic separation between the primary and secondary circuits. This double isolation results in a very low leakage current of less than 500µA and, as well as this, we've designed a toroidal-core insulation transformer to conform to the strict air and leakage clearances."
The new REOMED transformer was tested in REO's testing facility in Pfarrkirchen, Germany. Having built a wealth of experience, the facility develops and produces REO transformers for medical applications conforming to global standards and setting a benchmark for risk-free operation and efficiency.
