Isolation transformers receive medical certification

Power quality specialist REO UK has launched the latest edition of REOMED, a range of medical isolation transformers (MIT) for the galvanic and safe isolation of medical equipment from the mains supply.

This latest generation has been designed to comply to the 4th edition of the IEC/EN60601-1 medical use directive, the safety standard for medical electrical equipment and any additional equipment used in a medical environment.

Medical environments require increased air and creepage distances, and these are achieved by using a special toroidal isolation transformer. The IEC/EN60601-1 standard applies to the basic safety and performance of medical equipment or systems, in the presence of electromagnetic disturbances.

The standard requires equipment to be able to safely remove the connection between neutral and earth, which exists in a normal un-isolated system. The fourth edition REOMED series is certified for power ranges up to 2,200VA and can be manufactured according to a manufacturer’s design or electrical engineer’s specifications.

Medical isolation transformers are critical in environments where there are several life-support machines with other medical and commercial equipment in close proximity to one another. Without isolation transformers, the medical equipment could be compromised and put patients at risk of an electric shock.

The REOMED has been designed to reduce the maximum leakage current. It has been created to feature a thermal sensor, which will cut-out in the event of an overload, and will restart again when cooled down. An earthed copper screen guarantees that leakage current is further reduced to well below specified limits, adds REO UK.

The REOMED isolating transformer can be supplied with features such as half-wave failure detection and inrush current damping. The device is also available for use on a mounting rail and several other accessories such as the REO ISOMonitor, which can provide a direct connection to the REOMED output socket and sensor connection socket.
