VPT’s Entire SVR Space Series Now Registered with Defense Logistics Agency

November 7, 2013 | Press Releases

Official Standard Microcircuit Drawings Issued for VPT’s Entire Rad Hard DC-DC Converters and EMI Filters Series

BLACKSBURG, VA, Nov. 7, 2013 – VPT Inc., a HEICO company (NYSE:HEI.A) (NYSE:HEI), announces the release of Standard Microcircuit Drawings (SMDs) by the Defense Logistics Agency (DLA) for VPT’s entire SVR Series of radiation hardened DC-DC converters, point of load converters, and EMI filters. VPT’s SVR Series products were developed specifically for the most extreme requirements of space systems.

The SVR Series, which includes 24 modules in seven product families, is suited for use in LEO, MEO, GEO, deep space and launch vehicle programs and was initially introduced in May, 2013. SVR Series products feature maximum levels of radiation hardening with a Total Ionizing Dose (TID) of 100 krad(Si) and SEE of 85 MeV-cm2/mg. The SVR Series is based on space-proven heritage designs and available qualified to MIL-PRF-38534 Class H and Class K.  These are the first power conversion products commercially available that are designed and manufactured in accordance with Aerospace Corporation’s Technical Operating Report (TOR) requirements for space power systems.

 “Our broad offering of space qualified products are proven in programs like Venus Express, GPS III, Mercury Messenger and many others,” said Monty Pyle, Vice President of Sales and Marketing. “We are extremely pleased with the adoption of our SVR products into new critical space developments to date, and with the DLA’s approval of the reliability and radiation performance of our entire SVR space series, engineers can readily select modules from SMDs with maximum levels of radiation hardening that are qualified to MIL-PRF-38534 Class H and Class K standards.”

About the SVR Series of Space Qualified Power Products

The SVR Series performance in space programs is guaranteed through the use of radiation hardened semiconductor components, radiation lot acceptance testing (RLAT) of non-hardened components, and analysis. The SVR Series is characterized for TID performance including ELDRS and SEE according to VPT’s DLA-approved Radiation Hardness Assurance (RHA) plan per MIL-PRF-38534, Appendix G, Level R. Characterization is performed at both the component level and at the SVR Series hybrid level.
