Controlled Power Company (CPC) is one of only a handful of original power conditioning manufacturers to have survived the merger acquisition frenzy over the last two decades leaving their competitors, most of which have disappeared or merged endlessly into obscurity, far behind. 

As a groundbreaker company, CPC is often overlooked but due to the attrition in the power conditioning market, has evolved into a broad-line manufacturer offering traditional power conditioning products, transformers, and a specialty line of emergency lighting inverters.

Gruber Power sells and offers global service and all CPC products.   Click here to see our refurbishing center and depot repair facility.
