Amgis Toroidal Power Products

Custom Toroidal Transformers

At Amgis, LLC, we have long considered custom toroidal transformers to be our specialty. Perhaps you are encountering obstacles where a traditional transformer is incompatible with your application--the voltages or power ratings don't match, the units do not fit your available space, the application requires specific voltages, more winding. These situations are when the engineering team at Amgis shines the most

In the past, we have worked primarily in providing custom products in industries such as industrial, medical, instrumentation, renewable energy, and audio. We are equipped and ready to create custom made transformers for the following applications:

  • Medical Isolation Transformers
  • Toroidal Power Transformers
  • 3-Phase Toroidal Transformers
  • Auto Transformers
  • Audio Transformers
  • High-Efficiency Transformers
y

We have the capability to customize toroidal power transformers for 1.6VA -15,000VA requirements at 50/60Hz or 400Hz. They are UL-recognized under our UL5085-1 family file. We also offer UL recognized Class B, F and H insulation systems.

At Amgis, our lead time is not any longer for our custom toroidal transformers to produce than it is for our standards. We can produce prototypes quickly for custom parts and designs, often in 1-2 weeks. Our wide range of experience with custom applications gives you the advantage in the long run. When our expertise is combined with our state of the art proprietary software, low lead times, efficiency, and short design development times for customers, our services can't be matched. Contact us today and get a quick start on solving your transformer needs with a custom transformer from Amgis.

 

Please fill out our custom design form and we will look for your best solution to your toroidal transformer need. You can also request us to contact you by fill in the Quick Contact form to the right. We appreciate your consideration of Amgis for your power needs and will get a custom quote or solution to your requirements as promptly as possible.
