Renewed medical transformers: Innovation that combines higher safety with lower cost

The new medical transformers (TMHD) from EREA focus on efficient energy consumption. As a result they offer the lowest Total Cost of Ownership (TCO) on the market. These transformers soon pay for themselves with the lower energy bills. But that’s not the only innovation. They are also even more reliable and safer than the previous generation.

EREA continues to go the extra mile in differentiating the range of medical transformers. The classic series is further optimised as regards price, while performance stays the same. You then benefit from the lowest entry cost. Far-reaching development work has resulted in the EREA energy efficient series (BTE series) being a further 10 to 15% more efficient without affecting the price. The cost recovery time compared to the classic series is then further minimised. As a result you have the lowest Total Cost of Ownership (TCO) on the market. These transformers pay for themselves with lower energy bills.

”Ordinary” versus medical transformers

Transformers must obviously comply with a number of general conditions set out in law. On top of these requirements medical transformers must also be in compliance with European harmonised regulations: HD 60364-7-710. The medical transformers from EREA Energy Engineering obviously satisfy these requirements.

More reliable and safer

In line with the standard above, the revamped medical transformers from EREA Energy Engineering are provided with double or reinforced isolation, not only between the primary and secondary windings, but also between the windings and the transformer core. EREA continues to fit its medical transformers with an Earth screen between primary and secondary windings. That makes them even safer. The built-in temperature sensor ensures an early warning if the transformer is becoming overloaded.

To link with isolation monitoring

Under the Belgian regulations for electrical installations the TMHD medical transformers must be connected to an isolation monitor by law. This is important should an isolation fault occur in the medical IT network system. Although the system continues to work after a first fault, it is important that the fault is detected as quickly as possible. That is the purpose of the isolation monitor. EREA also has solutions available here. This can be with or without link (communication) to a building management system.

Properties of the medical isolating transformers

  • Limited no-load current (< 3% In)
  • Limited inrush current (< 8 x In)
  • Limited leakage current (< 500μA)
  • Earth screen between primary and secondary windings
  • Internal temperature monitoring with sensor
  • Low Total Cost of Ownership (TCO)

Don’t wait to get the benefits from our medical transformers!
