SDS2 Trip Computer CPU Power Supply: nuclear reactor

---

Nuclear power plant owners have expressed recent concerns regarding the quality of replacement power supplies from some vendors because of use of commercial components of sub-standard quality. To address this issue, Tyne designed its power supply from scratch, using custom-wound transformers, and all components positioned for easy inspection by Tyne Engineering and it's customers. 

During re-engineering, Tyne was able to incorporate improvements based on customers' operating experience with previous power supplies. Improvements included better accessibility of test points and better cable routing to allow easier maintenance, installation and replacement.
