Transformer for rooms used for medical purposes

Transformers for rooms used for medical purposes are isolating transformers in accordance with EN 61558-2-15 with double or reinforced insulation. A shield winding is fitted between the input and output winding, which is connected to an insulated connection terminal. Single-phase transformers have a center tap for connecting an insulation monitoring device on the output side. The rated voltage on the output side must not exceed 230 V (for three-phase transformers between the outer conductors). The transformers are used to supply rooms used for medical purposes in hospitals and doctors’ surgeries. Switching off due to overload is not permitted with these transformers. Monitoring (temperature or current) with visual and audible alarms must be provided to control the load.

Inrush current: 12-fold IN
No-load input current: max. 3% of IN
Short-circuit voltage uk: max. 3%
Power: 3.15 – 8 kVA
