KOEN Meets the Demands of
SOSA-Aligned Power Supplies within
MOSA Principles

SOSA® (Sensor Open Systems Architecture) has emerged as a leading standard, defining key technical requirements for embedded systems with MOSA principles (Modular Open Systems Approach). As SOSA-aligned platforms become more compact, rugged, and power-dense, power supplies must meet increasingly stringent performance and interoperability demands.

Technology Driven and Reliability Focused Approach to Power Supplies

Form Factor and Interoperability

When designing SOSA-aligned power supplies, form factor choice is crucial for integration and performance. At KOEN Power, we use the 3U form factor, which strikes a strong balance between power density and space efficiency in VPX systems. While SOSA supports multiple options, 3U stands out for its modularity and compliance, making it well-suited for rugged defense and aerospace use. Engineers should weigh electrical, thermal, and mechanical needs—especially alignment with SOSA slot profiles—where 3U offers proven flexibility and long-term viability.

Power Density and Efficiency

At KOEN Power, our SOSA-aligned power supplies are designed with a focus on high power density and efficiency to support the demanding requirements of today’s compute-intensive and RF-heavy payloads. Our solutions deliver more power in compact 3U VPX footprints—without compromising thermal or EMI performance. As system integrators push for better SWaP and modular compliance, KOEN’s power modules stand out for their ability to deliver consistent efficiency across load ranges while meeting the strict electrical and mechanical standards outlined in the SOSA Technical Standard.

EMI, Environmental & Survivability

SOSA-aligned power supplies for mission-critical defense systems must adhere to stringent EMI requirements, including MIL-STD-461, to prevent interference with sensitive avionics and communications. Robust filtering, shielding, and grounding techniques are essential to achieve low radiated and conducted emissions. Environmentally, these power supplies are engineered to withstand severe temperature ranges, shock, vibration, and humidity per standards such as MIL-STD-810, ensuring reliable operation in rugged field conditions. Survivability is enhanced through fault-tolerant designs, redundant protections, and ruggedized packaging that maintain functionality under electrical transients, mechanical stress, and electromagnetic pulse (EMP) events, thereby safeguarding continuous mission-critical performance.

Telemetry and Health Monitoring

Advanced digital control architectures enable continuous monitoring of key parameters such as voltage, current, temperature, and fault conditions, providing critical insights into power supply performance and health. This telemetry capability supports automated fault detection, isolation, and recovery (FDIR), reducing downtime in mission-critical defense platforms. Integrating these monitoring features within the SOSA framework ensures standardized data interfaces and interoperability, facilitating streamlined system-level diagnostics and lifecycle management.

Scalability and Upgradability

MOSA’s open architecture enforces standardized hardware and software interfaces, enabling seamless component interchangeability and multi-vendor integration. This approach reduces total lifecycle costs through increased component reuse and mitigates supply chain risks via supplier diversity—both essential factors for maintaining platform sustainability and adaptability in rapidly evolving threat environments.
