Prototype your custom transformer

We can work with your engineers to develop prototype parts or specialized “one-off” units. Our custom transformers can be ordered as single orders or in small batch quantities for low production run components.

Production-run custom transformers, designed to meet price-points and lead-times

While we place a great deal of effort in developing a prototype unit that meets customer requirements, our facilities can be easily scaled to meet production level demand. With over 65,000 sqft. of manufacturing space, and multiple ISO registered production facilities, we are easily able to accommodate increasing production demand and meet customer lead-times.

Capabilities & Options

Our custom transformers can be combined with a wide range of options and design criteria. Whether world-wide voltage inputs, circuit protection devices, low inrush or noise attenuation is required, QT&E engineers and sales staff can work with you to determine a specification that includes all your design requirements.

Designing for Weather and Other Environmental Conditions

Our custom transformers can be designed to meet numerous weather and environmental conditions. We have designed and manufactured units to operate under potential circumstances in innovative ways, including numerous types of NEMA and IP-rated enclosures, cast coils, and more. We have custom transformers that have been in operation for over 30+ years in semi-exposed environments and that continue to perform to design specifications. Conditions to consider when developing project specifications include:

  • Wind
  • Snow
  • Heat and Cold
  • Salt
  • Rain
  • Sand and conductive sand
  • Caustic chemicals
  • High elevations
  • Down-hole environments
  • Marine and seaboard units

Power Transformers for World-Wide Use

Our transformers can be designed with custom voltages and taps to ensure operation under numerous electrical and geographic conditions. While common voltage taps can certainly be designed into your part, (i.e., +/- 2.5, 5, 7.5, and/or 10%), specific voltage(s) and tap(s) can be accommodated.
