Medical transformers
Transformers for medical purposes MED
They are used to supply power to medical premises, operating rooms, medical surgeries, etc. They provide electrical safety for patients and staff against electric shock, but also safe and reliable power supply in operating rooms or intensive care units.
The rooms that are powered by a medical transformer have a separate isolated network established. Medical transformers with higher performance up to 10kVA are usually used to power operating rooms or bed sections in hospitals.
In our portfolio we offer medical transformers with standard power of 1 - 10kVA with weight from 20 to 100 kg, which can be installed in electrical switchboard or outside the switchboard in a metal casing with IP23 protection. PT100 or Ptc thermistor thermal sensors are installed to monitor the temperature of the transformer. Given the important function that medical transformers have in healthcare facilities, it is recommended to purchase them from verified, reliable and certified manufacturers.
ELSIM s. r. o. is your responsible partner in the field of custom transformer manufacturing.
