Military Ground Power Systems

Tactical ground equipment must survive temperature extremes, sand and dust exposure, explosive shock, and the mechanical stress of cross-country mobility. Power supplies face input voltage variations from vehicle electrical systems, must maintain operation during engine cranking events, and need to provide clean power to communications equipment, fire control systems, surveillance sensors, and computing platforms. Horizon PSS specializes in compact, lightweight power modules for portable systems and ruggedized enclosures for vehicle-mounted applications, ensuring reliable operation in forward operating environments where field repair is not an option.

Our ground system power supplies conform to these military specifications:

• MIL-STD-461 – EMI/EMC requirements for ground vehicle electronics
• MIL-STD-810 – Environmental testing including temperature, humidity, sand, dust, and shock
• MIL-STD-1275 – Vehicle electrical system characteristics and test requirements
• MIL-STD-704 – Aircraft electric power characteristics (for ground support equipment)
• AS9100 – Quality system requirements for defense applications

Horizon PSS brings extensive experience in vehicle power architecture design, including battery voltage input ranges, spike suppression, and reverse polarity protection. We provide full qualification support, including EMI testing coordination and environmental stress screening programs. Our engineering team understands the procurement challenges of ground vehicle modernization programs and autonomous platform development. We offer transparent NRE estimates, defined compliance pathways, and production scalability planning. Whether your program requires COTS-based modification or fully custom designs, we deliver RFQ-ready power solutions with configuration control, obsolescence management, and long-term production support that de-risks your program timeline and lifecycle sustainment planning.
