Power stages remain a common failure point in defense and aerospace systems. What if one module could remove that risk without a redesign?
When we build electronics for defense or aerospace platforms, our biggest problem is not the logic or the RF — it is keeping the power stage alive in a harsh, noisy, mission-critical environment. We need isolation, we need protection, and we need something that does not force us to stack multiple blocks just to meet basic compliance.
That is what the GRD 50A M series from Gaia Converter solves. Instead of using separate converters, filters, and isolated stages, this family packs the required protection and conversion into one rugged 500 watt module that is already aligned with COTS expectations. That means fewer parts to qualify, less wiring, and fewer unknowns in the failure chain.
We can drop it into land vehicles, avionics racks, shipboard hardware, high power lighting, or directed energy payloads without worrying about it breaking under vibration or transients. The 1500 Vdc primary to secondary isolation and 500 Vdc chassis isolation remove cross fault risk, which is a common failure driver in mixed voltage defense electronics.
Because programs differ, the series ships in multiple variants: B board only, V coated, and P parallel. That lets us pick what fits the integration strategy without redesigning the environment around the supply.
