Ground Support Unit

The Department of the Air Force (AFMC‑AFTC, FA9302) has issued a Sources‑Sought Request for Information (RFI) for a commercial Ground Power Unit (GPU) to support aircraft start‑up operations for the 420th Instrumentation Group at Edwards Air Force Base, CA (ZIP 93524). Responses, due by 15:00 hours on 20 April 2026, must be submitted via email to Jaymi Taplin (jaymi.taplin@us.af.mil) and Christina Day (christina.day.6@us.af.mil) and should include only a commercial solution—no pricing or unsolicited quotes. The government will not evaluate submissions as proposals, will not reimburse any response costs, and does not guarantee a follow‑on solicitation. The required GPU must deliver at least 600 A continuous at 28 V DC (adjustable 24‑31.9 V DC) with an optional 400 A limit, and provide engine‑start capability of 28 V DC at 2000 A. Input specifications include three‑phase 400 V ±10 % or 460 V ±20 % at 50/60 Hz, 6‑pulse rectification, 29 A line current, 0.91 power factor, and a soft‑start inrush. Output performance must meet <2 % ripple at full load, ≤0.5 % voltage regulation from no‑load to full‑load, and 3 V / 600 A voltage compensation (manual or feedback). The unit should weigh approximately 120 kg (fixed) or 240 kg (mobile), operate from –40 °C to 56 °C, 10‑100 % non‑condensing humidity, generate ≤65 dB(A) at 1 m, and achieve 0.87 overall efficiency (130 W standby, 330 W no‑load losses). Overload capability must cover 600‑2400 A for durations from 30 seconds down to 2 seconds, with a proven MTBF of 100,000 hours, ventilation of ≥25,000 hours, MTTR ≤20 minutes, and communications via TCP/IP and USB. The GPU will be mounted on a towable trailer that raises the power supply and cables 18 inches off the ground for safety.
