With experienced engineering, efficient custom and standard designs, special construction techniques and processes, cost-effective manufacturing and excellent service, Powertronix guarantees all of its products to our customers.

Our production cycle includes a dedicated prototype division with complete representation of mass production critical machines and all other equipments. This dedicated prototype division ensures quick turn around time from transfer prototype stage to mass production.

Our prototype engineering and operation work force are energetic, creative, innovative and open-minded. They are always exploring possibile of improvements.

If the project is complicated, prototype and production work together to run a pilot batch to reassure that the entire process has been properly communicated among all parties.


Why prototype:

  • Research and identify all application requirements
  • Ensure all Powertronix product meets the application requirements
  • Verify all specification requirements have been addressed
  • Identify design issues and provide verification
  • Identify practical mass production issues and repeatability
  • Manufacturing cost analysis and verification


Powertronix Transformer Testing

With experienced engineering, efficient custom and standard designs, special construction techniques and processes, cost-effective manufacturing and excellent service, Powertronix guarantees all of its products to our customers.

Powertronix invests heavily in product testing equipment and test resource personnel. We can simulate multitudes of load and circuit possibilities with the wide range of test equipment.

We perform extensive series of tests at the prototype stage to verify the prototypes prior to mass production. Some of the detailed test results provide invaluable feedback to our design simulations. We constantly look for continual improvements to optimize the product development iterations and effectiveness.

Our mass production testing is based on international standards. Mass production is automated and keeps all our transformer test records to monitor the batch consistencies and continual improvements.


Some of theses tests include:

  • Core magnetizing current
  • No load voltage
  • Hi-pot test
  • Copper and core losses
  • Winding resistance
  • Phase tests
  • Leakage current test
  • Load test
  • Temperature tests
