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 Transformers from General Transformer

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.

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

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.

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.

Custom Transformer Typical Applications

Our custom transformers provide the efficiency, reliability, and quality that many industrial applications require. Whether you need a space-saving transformer for a compact application or a solution for a power generation application, we offer the custom transformer to meet your design needs.

Applications of our custom transformers include:

  • Power supplies
  • Circuit Control
  • Portable Power distribution
  • Battery chargers
  • Inverters
  • Ac filter inductors (reactors)
  • Dc smoothing inductors (chokes)

Ratings and Sizes of Custom Transformers

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.
