This opportunity is for a DLA Weapons Support procurement of a power autotransformer under NSN 5950-00-620-2911. The approved sources are Superior Electric Holding Group, Staco Energy Products, and OECO, each with specified part numbers. The part carries an AMC/AMSC code of 1C, meaning it is suitable for competitive acquisition but requires engineering source approval to ensure part quality.

Companies capable of manufacturing the item may submit information to the contract specialist for review.
