Low Voltage Dry-Type Transformers

Maddox’s customer service team (Cameron) was incredibly helpful and efficient. They resolved my issue quickly and were very pleasant to work with. I would definitely recommend this company to others.

Very easy company to do business with, my order showed up on time and everything was in new condition. No dents,dings etc. Thank you for a good product , working great for us.

I needed a transformer for an Australian piece of equipment that operates at a non-standard (in America) voltage. Maddox tech support was able to verify which transformer would work for my application. They also had the unit in stock and shipped it to me in just a few days! A great experience all around.

It was what our Team was looking for. We really appreciate the updates and customer service after placing the order

Easy transaction, competitive pricing. arrived on time and in excellent condition... I'm happy to do business with Maddox again.

Great experience from shopping to ordering, to product. Customer service answered all my questions. Highly recommended.

Absolutely the best for every need that I have had. Several of my client pieces of equipment that require European voltages. Maddox has been my go to as most my daily distributor and venders don't have a clue. Plus Customer technical support is always spot on.

Maddox helped us find the right product and even found a rebuilt unit that met our needs and saved us $. Also, great turn around on delivery along with the communication and follow-up.

The manufacturer was very helpful in providing details on how to use and configure. The transformer is very versatile and can be reconfigured for different input voltages.

I purchased a Transformer from Maddox. They explained everything to me about what I needed. It was in stock. They arranged the shipping and was delivered to my customer right away. The service was prompt and professional.

This product works fantastic for my office. It is used to supply voltage for an EV charger and works flawlessly.

Couldn't ask for more! It was easy to find the right product using the website. Purchasing online was simple. Delivery was fast.

Order shipped and arrived within the week, unit in excellent condition, could not ask for better customer service!

The transformer works great! It allows us to run our 480v moulder/planer with our 240v electric service. The service techs were excellent with answering any questions I had about installation and operation.

I love Maddox! I wish I had the opportunity to order from them more frequently. Always so helpful and fast shipping

I got this delivered in just a few days. The tech support guys helped me pick the correct transformer for my application. I’m stepping up from 208 to about 380 for a foreign made packaging machine. I also like that the transformer has multiple legs so I could use this for a different application someday.

Maddox was great to work with! They supplied a quality product and were able to do so with a quicker turner around time then similar vendors. I will consider them for future projects.

Puchaced a reconditioned 3 phase 30KVA 480^ - 208/120Y dry type general X-former for a reasonable price. Delivery was quick and packaging was tight with all the KO punched in the past sealed up. Will use them again for future X-former needs.

I order a used transformer, but the one I received looks brand new! Old Dominion delivered this at noon today (Monday, July 13). I ordered it Friday (July 10)...if this 400 lb transformer had been a 5 oz FedEx overnight envelope, it would not have arrived faster than Maddox got it here. 'Most excellent'.

Your service and response was impeccable. T he equipment quality is excellent. It was a pleasure to work with Jeremiah. He was fantastic, sent me all the drawings and paperwork superfast. Can't wait to need another transformer. Thank you very much.

Needed a smaller 15kva transformer for my client and Maddox had one delivered on site within 5 days. Timing is everything to us electricians in the field and miles with Maddox is my new transformer sales rep! Thank you guys

Excellent customer service and transaction overall. Will definetly keep doing business with Maddox in the future.

Competitive pricing, always the most inventory, and exceptional after sales support. They are my "go to" option for transformers

This unit works exactly as expected. Great customer service. Couldn't ask for a better experience. Highly recommend this company!!

This transformer did exactly as it is supposed to. Perfect fit, and very quick shipping. Maddox guys are real pros!

I was delighted to find this transformer in stock and shipped immediately. It showed up fast. Exceeded my expectations. Thank you!

I have used Maddox a few times for transformers, but moving forward they will be my number one source. They have a great stock, always responsive, and a great product!

Good stuff made in Merica'. We have used Maddox in place of some major names like Schneider and Eaton due to lead times and price. This equipment does not disappoint.

I highly recommend Maddox for your transformer needs. Finding what is needed is a breeze and the prompt service is great not to mention the prices is wonderful too.

Had it In stock - reasonable price , shipped the same day - delivered within a 1/2 of the scheduled time - great job

Company rep very knowledgeable, friendly and proactive in helping me with my needs. Providing help each step of the way in my search for the right transformer. Inventory was good. Highly recommend.

These guys are great to work with! They have a ton of transformers in stock with quick shipping and even better prices, will definitely be ordering from them again!

Great sales department they had what I needed “112.5kva transformer “at a great price and with a lead time that was amazing as compared the parts house’s out here I will definitely be using Maddox in the future.

This is my 5th order from Maddox. Always knowledgeable and helpful. Every transformer I have purchased has worked perfectly.

Couldn't ask for better! From sales to shipping, to accounting. Item arrived as specified, expertly packaged for shipping, email notifications from all for tracking, billing, and assurance of delivery. It is so gratifying to know there are still companies and these kinds of people in the USA to deal with! Refreshing in these times.

Great transformer, great quality and excellent support that answered my questions in minutes even after the sell. Would recommend and buy again.

Super fast delivery and great communication. The transformer was in our warehouse in 3 days. That helped us get the job done fast.

This was my first purchase with this company. It was an easy experience purchasing the item I needed online. They offer a very competitive price, and the delivery was as promised. Look forward to doing more business with them in the future.

Purchased a unique transformer for a European machine. It was in stock and shipped within 24 hrs. Great service at a good value. Will be back to order more.

Maddox's commitment to customer service is evident by how they treat their customers. Richard, exemplified this in my recent interaction and through our interaction he has earned a continued customer. Thanks again!

Site was easy to pick out my 45kva step up. Click, pay, 4 days later it was at my shop being wired up. Have a 480 press brake but only 240 so this was exactly what I needed.

As an electrical contractor, I'm always looking for top-notch talent. You'll find everything you need when it comes to transformers @ Maddox. Customer Service is 5 Stars!!!

Purchased transformer online. A representative contacted us promptly and handled any issues. Great to see there are still companies that care about their vendors. We will contact them again in the future.

Had a odd ball transformer no one had it but they did. Sent a truck from Jacksonville and they had it ready when I got there thank you.

We ordered a transformer from Maddox Industrial and it was such quick and easy service. The product shipped immediately and arrived with no issues. Highly recommend this company. We will be using again! - Purchasing | Alabama Specialty Products Inc.

John and Richard are absolutely fantastic to work with and will go above and beyond on communication, kindness and getting you taken care of. One of the best teams I’ve ever worked with.

I have been very happy with the three 15kva transformers we purchased from Maddox. The team is ready to please, friendly and actually helpful. The cost vs quality is unfounded. Shipping for these larger units was surprisingly fast too. We will definitely be doing business with them in the future!

Service was great, all was received in good order and quickly and the communication on status and shipping info was excellent as well. Would definitely use them again for any transformer needs and recommend them to others.

The people I dealt with were great! They were happy to make changes last minute on my order, when I messed up, and quickly remedied my concerns. Will definitely deal with them in the future

Professional, reliable, fast. Maddox has been a great company to work with. They have had very quick responses, the website is very user friendly, and products show up within the appropriate time frame.

Purchased a step-up transformer from Maddox knowing nothing about them...These guys went above and beyond on top of excellent pricing. I honestly could fill this up with nothing but good things to say. If I could give them 10 out of 5 stars I would.

Great service and support. They make it easy, fast shipment, fair prices. If you need a reliable transformer in the US, and you one serious business, choose Maddox.

Greg went OVER AND BEYOND to get us what we needed on a holiday weekend. Without his assistance, our operation would have been in serious trouble. He helped us find the correct transformer and coordinate a pickup from the warehouse all within an impossible timeframe. Thank you thank you. Will definitely use Maddox for any future transformer needs.

I have purchased many pieces of equipment from Maddox ranging from 1000 kVA transformers to 10,000 kVA transformers as well as fused and non fused load interrupter switches. I am happy with the cost and the lead time which has been perfect for the fast paced schedules with tight budgets we have been facing. The customer service has been on the spot when questions arise.

Worked hard to meet my deadline. very helpful & knowledgeable.

Worked excellent, tech support was incredible with helping me figure out what I needed as well

Very responsive to inquiry, prompt shipping, protective packaging, on time delivery. Will be back!

Website was easy to navigate where I could order my own transformer with little assistance.

We had a customer who lost their primary transformer in the middle of the night. Maddox was able to get a temporary transformer on site in hours. They also rebuilt the damaged transformer in record time while no sacrificing any quality. I would recommend Maddox to anyone for transformer needs.

We worked with Maddox most recently to repair a transformer at our site. Cameron and the repair team were very communicative, professional, and understanding of our needs to get back online as quick as possible. We are very impressed with the level of service we received and look forward to working together in the future.

Very prompt delivery and service

We are a solar installation company based in MA. We've used many suppliers and distribution partners, and none have been as good as the kind folks at Maddox. They deliver high quality products on budget, and more importantly, on time. They've won our business for life and we'll continue to order from them for our commercial and utility scope projects.

It's good to find companies that make the buying process easy. I don't know if we'll need many transformers in the future, but I'll definitely be recommending you to our electricians.
