2113 SDS2 Trip Computer CPU Power Supply 電源

Tyne’s replacement power supply for the SDS2 Trip Computer CPU was designed to satisfy the demanding Nuclear Technical Specification of the original power supply that has been in service for 30 years. The new model has a completely redesigned circuit board using high quality, modern electronic components.

Tyne的更換電源為 SDS2 跳閘計算機 CPU 的設計, 以滿足苛刻的核技術規格的原始電源已在服役了30年。新的模型有一個完全重新設計的電路板使用高品質, 現代電子元件。

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 and its customers.核電廠業主最近對一些供應商更換電源的質量表示關注, 因為使用了分標準質量的商業部件。為解決這一問題, Tyne從零開始設計其電源, 使用自定義纏繞變壓器, 以及所有組件的位置, 以方便地檢查, 由 Tyne和其客戶。
