Custom Power Transformers

Transformers are electromagnetic devices which transform energy from an electrical circuit into energy in a magnetic circuit, and then back to electrical energy. Using this process, transformers can efficiently transfer power between two or more electrically isolated circuits or convert voltages and currents to desired levels. 

At General Transformer, there are no off-the-shelf transformers. All of our products are custom designed and manufactured to meet your individual design needs. Whether you need a specific temperature rating, size, or mounting configuration, we work closely with you to design and manufacture transformers with the proper magnetic topology for your application. 
 

Types of Custom Power Transformers

General Transformer designs and manufactures both single and three-phase transformers with toroid or laminated steel cores, with multiple windings, taps, and other features as required for your specific application. In addition, General is one of the leading producers of constant voltage ferroresonant transformers.

Ferroresonant Transformers

These custom ferroresonant transformers provide reliable regulation with the rugged design your application needs. They protect sensitive loads from noise, surges, and other disturbances.

Toroidal Transformers

These custom transformers are designed for compact applications, provide high efficiency in a smaller size and lighter weight.

Three-Phase Transformers

For higher power ratings, we design and manufacture custom three-phase transformers that are a cost-effective, high-quality option for industrial applications.

Custom Inductors

Our inductors are custom designed and manufactured to meet your needs, whether that’s multiple windings, taps, or a gapped steel core.

Line Conditioners

Our unique series of line conditioners, the EMAX Defender series, offers the durability and efficiency needed for sensitive electronic equipment.

Low Frequency Transformers

General Transformer works with many industries for varying applications in need of a custom low frequency transformer. We provide low frequency transformer designs with frequency capacities of:

  • 50/60 Hz
  • 60 Hz
  • 400 Hz

Your frequency needs will vary depending on your specific application and geographic location. For instance, North, Central and South America typically use 60 Hz while the rest of the world is more likely to use 50 Hz. Most 50 Hz low frequency transformers can be used in a 60 Hz application and usually have a 50/60 Hz rating. A 60 Hz rated transformer should only be used in a 60 Hz application.

The 400 Hz low frequency transformer is used in high-powered applications to minimize size. Smaller and more lightweight than a 50 Hz or 60 Hz transformer, a 400 Hz transformer is especially suited for military, aerospace and avionic applications as it allows for increased cargo space and decreased fuel consumption.

Applications of our custom transformers include:

Custom Transformer Factors to Consider

Available ratings depend upon several factors including:

  • Power requirements
  • Maximum voltages
  • Currents
  • Frequency.

We can produce laminated steel isolation transformers with ratings from 100 va to 60 kva for 50/60 Hz, operation, autotransformers to 120 kva, and transformers for 400 Hz operation to 20 kva or more.
