This is a sole source requirement for transformer modules intended for Vanguard Electronics LLC as the Original Equipment Manufacturer. The initial purchase is for 25 Transformer Converters, 50 Transformer Power, and 25 Transformer Power Step Downs, with options for additional quantities. The expected lead time is 120 weeks from award, and the total contract period should span approximately 730 days. The justification for the sole source is that using another vendor would cost over $750,000 and delay the schedule by several months for requalification. Delivery is Freight On Board destination, with inspection and acceptance at a government location.
