Custom General Purpose Transformers (Power Transformers) are designed to provide system power

Designed in a collaborative effort between your staff and ours, designs are available in:

  • Either Step-Up or Step-Down,
  • Single-phase and three-phase,
  • Multiple primary or secondary voltages accomodated,
  • Available open frame or in a NEMA rated enclosure,
  • With or without circuit protection.

Specifying General Purpose Transformers

Below are somethings that will be needed in order to properly specify your next transformer:

Power Rating Up to 1.5MVA
Frequency What frequency are you looking for? If you know what country your application will be in, but don't know the frequency, we have a list for common frequencies per country here.
Primary Voltage What primary voltage(s) do you need?
Secondary Voltage and Current
  • What secondary voltage and current will you need (multiplied together, these give you VA or kVA)
  • How many secondaries will you need?
  • If you have multiple secondaries, will you be using them at the same time?
Other Options What other value-added options do you need? We offer the following and more:
  • Enclosures
  • Casters
  • Circuit breakers
  • EMO switches
  • Fuses
  • Current-limiting designs
  • Low-inrush designs

If for any reason you are having trouble figuring out the above mentioned aspects of your next transformer, still feel free to give us a call. Our sales representatives are technical staff that can help you find the needed information.
