The first international expansion of the Digatron group was established in the USA when Digatron merged with a recognized and experienced USA manufacturer, Firing Circuits of Connecticut in 1988. It has remained a complete solution provider encompassing local manufacturing, sales, service & support in the USA since then. The incorporation of Digatron and Firing Circuits was a great technological fit, with Germany specializing in test equipment and the USA facility primarily designing and building formation rectifiers. This partnership expanded rapidly and is now renamed as Digatron Power Electronics Inc., making it the largest USA supplier of test and formation systems. Located in Shelton, Connecticut, the plant, with in-house engineering, manufacturing and service facilities, now provides the entire product portfolio of Test & Formation equipment for all battery technologies including the emerging lithium, electric vehicle, energy storage, and lead acid battery markets for North and South America.
