Winding goods for power supply systems

Smooth operation

For the smooth operation of power supply systems, maximum reliability, economy and robustness of transformers and chokes are a necessity. TRAMAG is your competent partner for winding goods in the application of power supply systems for stability of current and voltage for power supply e.g. of semiconductor factories.

Keep the voltage constant

We are very familiar with power supply systems: TRAMAG transformers and chokes can be found in UPS systems, AC and DC auxiliary power supplies, voltage stabilizer systems, voltage correction systems and step up / step down units. We offer further expertise in the field of filter circuit reactors for power factor correction.

Standards for power supply systems

Our products are certified as follows:

  • Construction and testing standard DIN EN IEC 61558
  • UL/CSA
  • Electrical protection classes I and II
  • Insulation classes B, F and H
  • Protection classes according to IP
  • DIN ISO 9001:2015

Individual and solution-oriented

Solution-oriented, economical, flexible: This is what distinguishes TRAMAG. Our chokes and transformers are also specially developed for the requirements of power supply systems and make a significant contribution to stable current and voltage supply in these systems. TRAMAG offers you products exactly tailored to your system.
