VPT Introduces 50V Input SVL Series of Space DC-DC Converters

October 13, 2021 | Press Releases

VPT, Inc. (VPT®), a HEICO company (NYSE:HEI.A) (NYSE:HEI), announces the availability of its SVLFL, SVLHF, SVLTR, and SVLSA Series of 50 volt, space-qualified DC-DC converters. Characterized by Total Ionizing Dose (TID) performance, including Enhanced Low Dose Rate Sensitivity (ELDRS), to 60 krad, the series is operable over the full military temperature range (-55 °C to +125 °C) with no power derating, and is suited for use in low Earth orbit (LEO), medium Earth orbit (MEO), geostationary orbit (GEO), deep space missions, and launch vehicle programs.

With a wide input voltage range of 30 to 60V, the SVL series of DC-DC converters are designed specifically for space applications facing harsh radiation environments, with guaranteed performance through the use of hardened semiconductor components, radiation lot acceptance testing (RLAT) of non-hardened components, and analysis.

SVLHF5000SF DC-DC Converter“The SVL families add 50V input versions that offer a wide input range of 30 to 60V with an 80V transient capability for the higher voltage satellite busses that are becoming more common worldwide.” Said VPT’s Vice President of Engineering, Leonard Leslie. “The new SVL 50V input series of isolated DC-DC converters meets the same radiation tolerance levels of the SVL 28V input series of 60 krads TID and single event effects capability with no destructive events to LET = 85 MeV/mg/cm2.”

The SVLFL (120W), SVLTR (40W), SVLHF (20W), and SVLSA (6W) will be qualified to MIL-PRF-38534 Class H and Class K pending DLA approval.

The availability of the SVL Series is subject to all applicable U.S. export license restrictions and regulations. Additional information can be obtained by contacting a local VPT distributor.
