Mission-Critical Electronics Expertise
Ruggedized Power Systems Engineered for Unforgiving Defense Operations
Defense programs require absolute reliability under extreme environmental stress. Premium PSU designs and manufactures specialized power electronics for European defense prime contractors and global systems integrators, combining 40+ years of power engineering with complete European sovereignty.
Our engineering headquarters in Barcelona manages every phase of project development—from initial topological selection, thermal FEA modeling, and planar magnetic design, through to qualification testing, RAMS analysis, and full SIL certification support.
Tailored Power Conversion Across Defense Platforms
Each operational environment presents unique electrical and mechanical stresses. Our custom and modular platforms are tailored to meet stringent military standards for land, naval, airborne, and critical defense infrastructure applications.
Patrol Vessels & Sub surface
Low acoustic noise and ultra-high galvanic isolation inverters and rectifiers built for radar suites, sonar arrays, tactical communications, and auxiliary power.
Air Defense & Avionics
Compact, high-power-density converters designed against DO-160G and MIL-STD-704 standards for military aircraft, unmanned drones, and stratospheric payloads.
C4ISR & Mobile Base Racks
Uninterruptible power architectures and static transfer switches ensuring continuous telemetry and operational command integrity under hostile conditions.
Core Technical Capabilities & Environmental Protections
Reliability is built into the thermal and electrical design architecture before hardware build begins.
Extended Thermal Performance
Full-load continuous operation from -40 °C to +85 °C using planar magnetics and high-efficiency resonant power topologies that minimize heat generation.
Hermetic & Rugged Sealing
Enclosures built up to IP68 ingress rating with specialized conformal coating, pot-encapsulation, and anti-corrosion surface treatments for maritime salt-spray exposure.
High Galvanic Isolation
Enhanced creepage and clearance distances providing up to several kV isolation between input, output, and chassis to safeguard sensitive downstream electronics.
Flexible Cooling Systems
Support for conduction cold-plate, natural convection, liquid cooling, or speed-controlled forced-air cooling depending on space and thermal constraints.
EMI/EMC Compliance Design
Integrated internal filtering designed to pass stringent MIL-STD-461 radiated and conducted emissions, eliminating interference with radar and comms.
Shock & Vibration Immunity
Structural validation against heavy shock, drop, and multi-axis random vibration profiles to guarantee continuous operation in tracked vehicles and aircraft.
Defense Electronics Standards & Certifications
All power conversion systems undergo rigorous testing to ensure full compliance with major international defense and aerospace specifications.
