Single-phase medical transformers, 2TTMED type
Purpose and design
Medical grade isolating transformers are designed to supply power to medical and hospital premises. These transformers have very high technical requirements to guarantee safety and reliability. Idle currents, insulation leakage currents and transformer inrush currents are limited. Isolation is achieved by shielding and double insulation. Transformers on the secondary side have an additional 2M tap changer for connecting the insulation state indicator. Standard equipment includes temperature sensors built into the winding. Transformers can be supplied in enclosures with the required protection class.
Note:
Upon agreement, we can manufacture a non- standard device with the required technical parameters.
The manufacturer reserves the right to make changes to the parameters due to technical product developments.
