Event Description	The following is a synopsis of information received via fax: DRS Consolidated Controls Inc. (currently Leonardo DRS Naval Power Systems, henceforth referred to as NPS) provided eleven, 48 VDC power supplies, Part Number 16-AA T907B to Wolf Creek Generating Station in 2018. It was discovered in 2019 by Wolf Creek that there was anomalous fan performance occurring within this power supply after several months of operation.

NPS and the power supply manufacturer were notified of the issue to begin investigation on root cause and remedial actions.
