VPT (VPT®), a HEICO company (NYSE:HEI.A) (NYSE:HEI), announces the availability of its SVLFL, SVLHF, SVLTR, and SVLSA Series of 28 volt, space-qualified DC-DC converters. With a wide input voltage range of 15V to 50V, 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.
Characterised by Total Ionising Dose (TID) performance, including Enhanced Low Dose Rate Sensitivity (ELDRS), increased to 60krad, 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 programmes.
“The SVL Series of isolated DC-DC converters improve on the established legacy designs of the SV Series by raising the single event effects capability with no destructive events from LET = 44MeV/mg/cm² to LET = 85MeV/mg/cm².” VPT’s vice-president of engineering, Leonard Leslie, stated. “This upgrade to the SV Series gives customers a much more robust radiation-tolerant option from VPT making the SVL Series a cost-effective solution for many space applications.”
The SVLFL and SVLTR are qualified to MIL-PRF-38534 Class H and Class K, and Radiation Hardness Assurance (RHA) Level R, while the SVLHF and SVLSA have been submitted for qualification.
The availability of the SVL Series is subject to all applicable US export license restrictions and regulations.
