Developed for TOR Compliance | Rad Hard | MIL-PRF–38534 Class K

Create a reliable power distribution system with a complete array of radiation tolerant or radiation hardened isolated DC-DC converters, radiation hardened non-isolated point of load converters, and radiation immune EMI filters in varying TID and SEE levels to fit LEO, MEO, GEO, deep space, or launch programs.

VPT offers two series of DC-DC converters and accessories designed, tested, and proven for the challenging environment of space:

The SVR Series

  • TID: 100 krad(Si)
  • SEE: 85 MeV-cm2/mg
  • Developed for TOR Compliance
  • MIL-PRF–38534 Class K
  • On DLA SMDs
  • DLA-approved RHA plan

The SV Series

  • TID: 30 krad(Si)
  • SEE: 44 MeV-cm2/mg
  • MIL-PRF–38534 Class K
  • On DLA SMDs
  • DLA-approved RHA plan

VPT offers decades of proven spaceflight heritage, standard military designs, and engineering models for fast design and prototyping.

Around the world, VPT customers are launching space programs powered by VPT. Organizations including NASA, ESA, SpaceX, Lockheed Martin, Orbital, and many others regularly rely on VPT’s proven power solutions to power critical space missions.
