Defense Procurement FAQ
Frequently Asked Questions by Military Systems Engineers
Key technical insights from our military application engineers to streamline your power specification process.
Our defense power systems are built to meet key standards including MIL-STD-461 (conducted/radiated EMC), MIL-STD-810 (shock, vibration, environmental conditions), MIL-STD-704 (aircraft AC/DC power quality), MIL-STD-1275 (28V DC ground vehicle input transients), and MIL-S-901D (high-impact shipboard shock).
MIL-COTS (Commercial-Off-The-Shelf) power modules significantly reduce NRE (Non-Recurring Engineering) costs and shorten development cycles. Because COTS units utilize pre-tested, field-proven topologies, defense OEMs achieve faster qualification times while maintaining high reliability.
Yes. Many military programs require modified COTS units featuring specialized ruggedized enclosures, custom connector interfaces, conformal coating, potting for extreme shock, or tailored output voltage settings to fit tightly constrained electronic bays.
Liquid cooling removes heat far more efficiently than forced air. This allows extremely high power density in 1U or sub-rack enclosures, eliminates noisy air fans, prevents particulate/water ingress into sealed chassis, and guarantees continuous thermal management in high-ambient environments.
Production follows AS9100 and ISO 9001:2015 certified workflows. Units undergo 100% automated functional testing, high-potential (Hi-Pot) safety testing, thermal cycling, and optional Environmental Stress Screening (ESS) before final dispatch.
