The IBM 01KV555 is a DCA-ZN power module, a 4400W Distributed Converter Assembly built for IBM’s z14 zSeries mainframe systems, with cross-reference numbers N37674, P20024 and K02448R. DCA modules of this type sit within the mainframe’s bulk power subsystem, converting the frame’s main DC bus voltage down to the levels the processor cage and I/O drawers actually need, with multiple DCA modules typically fitted per frame for redundancy. The “-ZN” designation identifies this specific module as the z14-generation DCA design, distinct from the DCA-BC/DCA-T19/DCA-SQ families used in earlier Power server and z-Systems generations. Tech-Star supplies the 01KV555 as a refurbished power module for engineers maintaining z14-class mainframe frames, UK-based and shipped worldwide.
