Industry Leading Power  Density for Tethered Drones

Fly more payload at a higher altitude with DRACO-XFMR a vehicle-side, high-voltage DC-to-DC converter for tethered platforms. Our DRACO technology allows designers to use longer and lighter tethers than would be possible with traditional converters. With an industry leading energy density of 6.9 Watts per gram, you can focus on your mission, not your power budget. Multiple DRACO-XFMRs can be connected in parallel to provide scalable power for even the most demanding applications.
