Product Focus PSDG‑48 Series : Rugged Multi‑Output Power Module for 24/28 V Systems
Newsletter – June 2025
1/ Optimized for Harsh Environments – Built for Defense & Avionics
In embedded aerospace and defense systems, the need for compact, reliable, and pre-qualified power solutions is critical. The PSDG‑48 Series was developed to address this challenge with a fully integrated power supply that simplifies system design while meeting the highest industry standards.
✔ Target platforms: Mission computers, communication units, display controllers, sensors, and electronic warfare modules
✔ Use environments: Fighter aircraft, UAVs, land vehicles, naval systems…
2/ What Makes PSDG‑48 Series Different?
- COTS Performance with MIL-Grade Robustness
Meets MIL‑STD‑461, 704, 1275, DO‑160, and ABD‑100 — helping reduce integration time and certification effort.
- Fully Integrated Protections
Built-in EMI filter, inrush limiter, reverse polarity and hold-up — no need for external circuits.
- Compact Multi-Output Design
Dual or triple outputs in a single, space-saving 91 × 54 × 9 mm module.
3/ A Solution That Simplifies Power Architecture
If you’re currently designing power distribution for a 28 V avionics system, for example, the PSDG‑48 Series can directly replace a full chain of:
- DC front-end filter
- Transient suppressor
- Multiple isolated DC/DC converters
- LDOs for low-voltage rails
✅ One part number, one module, tested and qualified.
