Powerbox ECDA Series - 470 W to 1,000 W Military-Grade Baseplate AC/DC Power Supply
IP65-Enclosed, MIL-STD-Certified Power for Defence and Harsh-Environment Applications
Power supplies intended for defence platforms, military vehicle systems, and ruggedised infrastructure installations face a fundamentally different specification environment from standard industrial products. Vibration and shock resistance, EMC compliance to military standards, operation across extreme temperatures, and a sealed enclosure that prevents ingress of dust and water are all baseline requirements - not optional enhancements.
The Powerbox ECDA Series has been designed from the ground up to meet these requirements as an off-the-shelf product. Combining conduction-cooled baseplate construction, an IP65-rated enclosure, conformal coating, MIL-STD-810H mechanical qualification, and MIL-STD-461G EMC compliance, it delivers between 470 W and 1,008 W of regulated DC output in a form factor built for deployment in genuinely demanding environments. FORTEC Switzerland offers the ECDA Series as part of its Powerbox defence and ruggedised power portfolio.
Designed for Defence, Industrial, and Infrastructure Applications
The ECDA Series is suited for deployment in applications where environmental robustness and military-standard compliance are fundamental requirements, including:
- Military vehicle, platform, and shipboard power systems
- Defence communications and electronic warfare equipment
- Ruggedised ground support and base station installations
- Industrial systems operating in harsh or exposed environments
- Infrastructure applications requiring IP-rated sealed enclosures
Military and Environmental Compliance
The ECDA Series is certified and qualified to the key standards required for defence procurement and deployment:
- MIL-STD-810H for vibration (Method 514.8, Figure 514.8E-1) and mechanical shock (Procedure 1, 20 G, 11 ms)
- MIL-STD-461G CE102 for conducted emissions and RE102 for radiated emissions
- MIL-STD-461G CS101, CS114, CS115, CS116 for conducted susceptibility
- MIL-STD-1399-300 for shipboard power system compatibility
- IP65 enclosure rating – fully dust-tight and protected against water jets from any direction
- Conformal coating of internal PCB assembly for additional protection against moisture and contamination
- EN 61000-4 series EMC immunity (ESD, radiated, EFT/burst, surge, conducted, magnetic field, voltage dips)
- EN 61000-3-2 Class A harmonic content compliance
- Safety certified to UL/CSA/IEC/EN 62368-1 3rd edition
- RoHS compliant (EU Directive 2015/863)
