The Original Solid-State Decoupler
PCR
Product Description
The PCR is a solid-state device designed to simultaneously provide DC decoupling and AC continuity/grounding when used with cathodically protected structures, such as pipelines, tanks, grounding systems, and cable casings. Commonly used to decouple electric equipment from grounding systems, for AC Mitigation projects, or other isolation and grounding applications, the PCR provides safety grounding while also isolating your cathodically protected structure, improving CP system performance. In addition, it features rugged, reliable performance and a wide range of ratings that make it suitable for a variety of applications. The PCR has been used by customers around the world and is the original solid-state decoupler offered to the industry.
