DLA-Aberdeen, for Army ILSC/SCMD/SSD, is conducting a market survey to identify additional sources for a commercially available 28VDC power supply used in Electronic Shop Vans/Transportable Electronic Maintenance Shops worldwide, not for design or development. The replacement supply must be an equal form/fit/function, drop-in/plug-and-play substitute that fits the existing electrical rack and interface cables, and offerors must provide specifications and technical proof of equality to P/N 005035003 (NSN 6120-01-508-1787) and P/N SGX30X334C-0ASAR (NSN 6120-01-508-1273). Bid sample electrical/mechanical inspections will be performed at Tobyhanna Army Depot during an Industry Day at a date to be determined/announced, with the government providing shelters/vans, power, and electricians. Requirements are indicated through FY31, and the Government does not possess or release a technical data package. This is for planning/market research purposes only, not a request for quote or proposal, and interested sources should email the requested questionnaire and supporting documentation, including company name, CAGE code, and technical point of contact.
