Medical Transformers

Function
ET3MED transformers are specifically designed to supply medical equipment in hospital group 2 rooms, where even minimal current flowing through a patient’s body may pose a serious risk to life or health. The transformer design complies with PN/EN 61558-2-15:2011, ensuring the highest level
of electrical safety. The units feature double insulation and an electrostatic shield placed between the primary and secondary windings, ensuring effective circuit separation and minimizing disturbances. Built-in PTC-120 sensors enable continuous temperature monitoring, increasing system reliability. As standard, transformers are manufactured with protection degree IP00
and can be vertically mounted using fixing brackets. Versions in enclosures with protection degrees IP23, IP44 and IP54 are also available.

Benefits

Maximum safety for patients and medical staff
Enhanced power supply reliability in critical applications
Protection of sensitive medical equipment against disturbances and overvoltages
Full compliance with applicable standards and industry regulations

Applications

Medical sector – in particular group 2 medical locations

Custom Design

Manufacturing a transformer with parameters other than those specified in the catalogue is possible upon prior consultation.
