Having the largest transformer inventory in the USA doesn’t help anyone without the team behind it. At Maddox we pick up the phone when you call and ensure you get the transformer you need when you need it.

Nice and easy transaction with good price and good delivery time.

My company ordered a new transformer from Maddox. Kurt was an AMAZING sales rep that listened to all my concerns and met them all with solutions that fit our timeline. Dale pulled off a miracle in getting our shipment on the road and delivered not only at the exact time I requested, but 2 hours early. I cannot express how happy I am with this company. They made me look like a hero! Which is exactly what THEY were to me.

Maddox Transformer offered a great buying experience. They had the transformer I needed at a great price and shipped it promptly! I received it the next day and am happy with the purchase!

Made an Online order. Maddox was extremely helpful and was emailing me with updates on my order. They even called to make sure that I would be available to receive the transformer or if they had to delay the shipment, as I ordered closer to the end of the year I really appreciate the dedication they showed to making sure I got the product I ordered. The unit arrived and works great.

Maddox website was easy to navigate, and showed what transformers were in stock. Luckily the step up transformer I needed was in stock, shipped within 24 hours, and was on my dock in 4 days. If you know exactly what you need, I would highly recommend Maddox based on my experience!

Maddox Transformers is a great company to work with... Circuit Breaker Sales in Florida has had great experiences with Maddox recently. Prompt responses to our requests and excellent work on reconditioning transformers. Very pleased with Maddox and will continue to utilize them in the future.
