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的更换电源为 SDS2 跳闸计算机 CPU 的设计, 以满足苛刻的核技术规格的原始电源已在服役了30年。新的模型有一个完全重新设计的电路板使用高品质, 现代电子元件。

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.核电厂业主最近对一些供应商更换电源的质量表示关注, 因为使用了分标准质量的商业部件。为解决这一问题, Tyne从零开始设计其电源, 使用自定义缠绕变压器, 以及所有组件的位置, 以方便地检查, 由 Tyne和其客户。
