About this opportunity
The U.S. Army Corps of Engineers, Portland District, is conducting a sources-sought market research activity for brand-name LTI Power Systems battery chargers and an inverter, with sources sought responses due May 18, 2026. This procurement is set aside for total small business and is not a formal solicitation under FAR Subpart 5.2.
The Government requires two LTI Power Systems 250A Rectifiers/Battery Chargers (Model LT3048HC) and one 15kVA UPS/Inverter (Model LT154848HD) to replace failing equipment at Bonneville Lock and Dam. Both units accept 480VAC, 3-phase input at 60 Hz and operate with 125VDC, 60-cell battery systems. The rectifier and UPS share identical NEMA 1 enclosure dimensions (31.5 inches wide × 65 inches high × 34 inches deep), with the rectifier weighing approximately 1,500 pounds and the UPS weighing 1,200 pounds. Both include external conformal coating on all printed circuit boards for moisture and corrosive environment protection and operate at acoustical noise levels below 70 dBA at one meter. The UPS includes an external manual bypass switch with two-position make-before-break rotary switching capability housed in a matching NEMA 1 wall mount enclosure.
Delivery must occur within 12–14 weeks of award, Monday through Thursday between 7:00 AM and 4:00 PM, excluding federal holidays. Responses should include a capability statement demonstrating ability to supply the identified requirements and clearly identifying any limitations.
