Benefits of choosing horizon for Space Grade DC-DC power supplies
As the exclusive representative of VPT in Israel, Horizon Electronics delivers flight-proven, space-qualified power systems that meet the world’s most rigorous standards. Our solutions support every phase of your mission from ground testing through launch and long-duration orbit.
Custom Engineering from Mission Requirements
Every system begins with your mission profile, radiation budget, thermal constraints, and form factor requirements. Whether you need topology optimization for a CubeSat PCDU or a rad-hard point-of-load converter for a GEO payload, we engineer solutions that match your specifications, not force-fit standard parts.
Designed for Harsh Radiation & Thermal Environments
Our systems withstand up to 100 krad(Si) TID and SEE levels up to 85 MeV·cm²/mg, while operating across wide thermal gradients and vacuum conditions. Designs undergo thermal vacuum testing, vibration qualification, and outgassing analysis per ASTM E595 to ensure survivability from launch through multi-year orbital operations.
Qualification Ownership and Standards Compliance
We manage qualification to MIL-PRF-38534 Class K, MIL-STD-461 for EMI performance, and MIL-STD-981 power supply space construction standards, along with NASA/ESA mission-specific guidelines. Our TID 100 krad power converter designs are qualified to withstand Total Ionizing Dose (TID) levels up to 100 krad(Si) and Single Event Effects (SEE) up to 85 MeV·cm²/mg. Designs undergo thermal vacuum testing, vibration qualification, and outgassing analysis per ASTM E595. Compliance documentation is structured to support your design review process, including radiation test reports, derating analysis, and failure mode assessments.
Clear NRE Scoping and Program Execution
We provide clear NRE scoping, realistic timelines, and milestone-based deliverables for space qualified power module RFQ responses. Our proposals include compliance pathways, qualification schedules, parts obsolescence mitigation plans, and configuration control protocols, giving procurement teams the information needed for satellite electrical power system program approval.
Lifecycle Support and Production Continuity
Horizon PSS maintains design authority and production continuity throughout your mission lifecycle. We manage obsolescence tracking, implement PCN (Product Change Notification) discipline, qualify replacement parts under configuration control, and support qualification updates as standards evolve. When your program extends or requires additional units years after initial delivery, we ensure consistent performance and traceability.
VPT Partnership for Flight-Proven Solutions
As the sole Israeli representative for VPT space-qualified power modules, we provide access to flight-proven hybrid DC-DC converters with heritage across military, scientific, and commercial space missions.
Space Power Applications:
Mission-Specific Engineering
Satellite Power Systems (LEO, MEO, GEO)
As a satellite PCDU manufacturer, Horizon PSS designs satellite power conditioning and distribution units optimized for mission orbit, radiation environment, and operational lifespan. Our LEO satellite power system solutions and spacecraft power converters balance efficiency, thermal performance, and redundancy requirements for Earth observation, navigation constellations, and defense communication systems. Designs accommodate thermal cycling between sunlit and eclipse phases, operate across wide input voltage ranges, and provide fault isolation to prevent single-point failures.
Deep-Space Probes and Scientific Missions
We provide custom spacecraft power converters and radiation hardened electronics for scientific instruments, propulsion subsystems, and communication systems operating in environments from inner planetary missions (high thermal flux, solar proximity) to outer solar system exploration (low power budgets, extreme cold). Designs prioritize fault tolerance, low electromagnetic interference, and precision regulation for sensitive measurement equipment across multi-year missions with no maintenance access.

Crewed Spacecraft and Orbital Stations
Our solutions meet human-rating requirements with low-noise output, fault isolation, and operational margins designed to prevent cascading failures. We support both primary and backup power architectures for environmental control, life support, navigation, crew instrumentation, and onboard computing, ensuring continuous operation even under single-point fault conditions.

Ground Testing and Hardware-in-the-Loop Simulation
Horizon PSS provides EM-equivalent power modules with programmability, telemetry interfaces, and thermal monitoring to validate system performance under simulated mission profiles. These solutions replicate flight performance, support thermal vacuum chamber operations, and integrate with hardware-in-the-loop (HIL) test setups while preserving flight units for launch integration.

CubeSats and NewSpace Platforms
We offer CubeSat power supply solutions featuring radiation tolerant DC-DC converters based on COTS-derivative designs with selective hardening, screening, and derating appropriate for missions under 5 years in LEO. These compact, lightweight power converters support remote sensing, experimental payloads, technology demonstrations, and constellation deployment at price points compatible with commercial space economics.
