Procurement FAQ

Frequently Asked Questions by Defense Buyers

Our military power conversion platforms are qualified against MIL-STD-810 (environmental), MIL-STD-461 (EMI/EMC), MIL-STD-1275 (28 VDC vehicle transient/surge), MIL-STD-1399 Section 300 (shipboard AC power), MIL-STD-704 (aircraft electrical power), and MIL-S-901 shock requirements. Tailoring is verified against your exact system specification.

Yes. Most military requirements can be satisfied faster and at lower cost by starting from a proven COTS or MOTS chassis and modifying connectors, output rails, hold-up time, EMI filtering, conformal coating, or mounting configurations. Clean-sheet custom designs are developed for strict form-factor requirements.

AJPS offers rackmount (1U-4U), half-rack, vehicle chassis, transit case, baseplate cooled, wall mount, and fully sealed IP65/IP67 waterproof and submersible power supply designs using circular MIL-spec connectors.
