SVCL2800S SERIES
SPACE QUALIFIED HYBRID INRUSH CURRENT LIMITER
Models Available
Input: 11 V to 50 V continuous, 80 V transient
100 W and 200 W versions
Qualified to MIL-PRF-38534 Class H and Class K
SVCL Series DC-DC Converter
1.0 DESCRIPTION
The SVCL2800S Series of space qualified Inrush Current
Limiters are operable over the full military (-55 °C to +125 °C)
temperature range with no power derating. The SVCL2800S is
designed to control the inrush current drawn by VPT’s EMI filters
and DC-DC converters during turn-on. The SVCL2800S
functions by limiting the rate of rise of its output voltage, and will
also control the inrush current of discrete input capacitors.
The SVCL2800S Series of Inrush Current Limiters is radiation
hardened and suited for use in low Earth orbit (LEO), medium
Earth orbit (MEO), geostationary orbit (GEO), deep space, and
launch vehicle programs.
