Transformer and Rectifier Service, Repair, and Upgrades

Tuesday, November 6th, 2018

At NEELTRAN, our customers always come first. With that in mind, servicing the DC Power Supply needs of our customers is a top priority here.

Whether it’s a Transformer Rectifier, Rectifier Transformer, Inductor, Reactor, Interphase Transformer, or any industrial power conversion/power electronics equipment, Neeltran’s service department of trained service engineers and technicians are waiting to serve you, in support of our own products, but ALSO for DC Power Supplies and Power Conversion products manufactured by others, too!

Many of the Power Conversion products (DC Power Supplies, Power Rectifiers, Rectifier Transformers) in the market have been installed in the 60’s, 70’s, 80’s and 90’s, and have effectively outlived their useful life. Many of these products are exhibiting inadequate performance and should be replaced or repaired/upgraded. Inadequate performance from a DC Power Supply ultimately means increased costs through lost production and increased maintenance costs.

Even if they are operating adequately, these units represent a significant threat to your production capacity in the event of failure.

Neeltran is completely equipped to handle all emergency and non-emergency repairs of Rectifier Transformers, Rectifiers, Controls (DC Power Supplies) either in-house or on site. We have invested in additional High Bay space with a large transformer pit and heavy duty overhead cranes.

Of course, Neeltran will service and support our own Rectifier Transformers, Rectifiers, Controls, Reactors, Inverters, Auto-Transformers, etc., but did you know that we also specialize in the repair and upgrade of existing OEM DC Power Supplies as well?

“Customers want to do business with real people that will take care of their short and long-term needs when it comes to critical power conversion equipment. By listening to our customers in the design process as well as the project management process, we’re able to accomplish that quite effectively.” -- Antonio Capanna Jr., President/C.O.O.
