At Neeltran we are uniquely positioned because we are one of the few companies in the world that designs and manufactures its own rectifier transformers and dc rectifiers in the same facility under one management team. This unique capability allows for combined Full Current and Full Voltage factory testing of the transformer and rectifier in their actual configuration prior to shipment.An experienced client requires combined testing to eliminate integration problems at the site and to assure the shortest commissioning time. This results in significant cost savings and produces the highest quality units. Most other Power Electronic System integrators purchase the Transformer from the least expensive sub-contractor, or they manufacture key system components in different geographic locations which operate under different management objectives.Our power conversion products and customer service are the best in the industry. Being that Neeltran designs and builds its rectifiers and transformers you do not have to deal with a 3rd party for service. Custom power systems manufacturing and engineering is what we do. Neeltran is ISO-9001-2015 certified.We service our clients from installation to end of life of product, nobody beats our service as we are on call for our customers and service many types of rectifier systems (including other brands).With Neeltran, your firm will gain access to our 45 plus years of proven Power Electronic experience, the latest technology and professionals who are enjoying world-wide recognition in this field. We offer a variety of types of rectifier products. We would welcome an opportunity to work with you on your next project!
