| Since 1963 we have
built thousands of converters, many as part of our own highly
regarded frequency control products. (Ninety-four satellite and space
exploration programs have used FEI precision time-frequency standards.)
We now offer proven DC-DC converters separately.
You can be confident that your decision to
buy from us is the right one, knowing that our units meet the highest
quality and reliability standards. In addition, buying from us (rather
than making yourself) usually means lower cost and faster delivery.
In many cases we deliver prototypes in only 4 months and flight
units in less than a year.
We are efficient, because we specialize in
supplying HI-REL products for space applications in relatively small
quantities. Quality, price and delivery advantages result from a
high degree of vertical integration. We maintain complete control
and responsibility throughout design and fabrication, particularly
over such crucial elements as...
Hybrid design and production winding
of magnetic elements
PC board fabrication
Modular design also shortens delivery and decreases
cost. We incorporate our proven modules using FEI HI-REL hybrids,
many of which are already qualified (and even in stock). FEI consistently
achieves the results that space demands. The technology is the latest
state-of-the-art that has been proven in use to be consistent with
Our units are designed to operate for 15 years subjected to natural
radiation levels of 107 rads and to survive man- made radiation
threats. Exposure of our integrated circuit chips and hybrids to
100,000 rads affects efficiency by only 1-2% as predicted to end-of-life.
Voltage tolerances are met with dose margins of 7:1 to over 100:1
without special shielding.
Efficiency as high as 85% is routinely achieved throughout design
life, even at environmental extremes. (When extra regulation provided
by the optional Linear Regulators is included, this drops only slightly
Proprietary design achieves light weight and small size by employing
our HI-REL hybrids, and low loss magnetics. We typically realize
power density of 0.18 W/cu. Cm (3 W/cu. In.) and 0.16 W/gm (5 W/oz.).
Output voltage protection
The Linear (output) Regulator, usually included to improve regulation
and minimize ripple, is specially designed to introduce a low voltage
drop, so that output voltage is only slightly less than input. Therefore,
should a failure occur in the regulator, the ouput rises no more
than 0.8 V ("headroom"). This often eliminates the need for an over-voltage
detector and shutdown circuit.
From APOLLO in 1963 to today’s satellite programs
such as TDRSS, our DC-DC converters (often included in our own systems)
have proven them- selves in space. For example, our converters are
on the ACTS and GPS satellites. (See below for a complete list of
FEI space and satellite programs.) Our numerous citations for quality
and contract performance have been Awarded by DOD, NASA and such
primes as Hughes, Ford Aerospace, TRW, E-Systems, GE and ALCATEL.
Currently, we supply 30-40 converters each year for satellites and
500 for aerospace and other HI-REL use.
Reaching the Highest of High
Our reliability record is one that any supplier must envy: Of our
more than 3,000 units on 90 satellite and space exploration programs
we have had only one reported anomaly!
This is not surprising considering our typical MTTF
is 5 x 106 hours without redundancy, which corresponds to 15 years
of life at a probability level of 0.9996 with redundancy.
Dedication to quality
Our exceptional reliability is also due to tight control of quality.
This is facilitated by a high degree of vertical integration, which
allows us to take full responsibility at every step.
The thin and thick hybrids we design and produce
(in Class 10,000 clean-rooms) meet levels S and B of MIL-M-38510
for prime contractors such as TRW, Hughes, GTE and GE.
Our certified instructors in turn train and certify
our operators to MIL-STD-2000. Our soldering meets WS-6536 (USN),
MIL-S-45743E (USAF) and NHB 5300.4 (3A1) (NASA).
Our management system focuses on quality and exceeds
the requirements of MIL-Q-9858A, monitored by DCAS.
Our PC board design and fabrication is QPL-listed
for MIL-P-55110D types GF, GY, GR, and GI and has been qualified
We are conducting a continuing TQM initiative to
produce the highest quality product.
Reliability by design.
This enviable record testifies to our dedication to reliable design
and process control. Wherever possible, proven sub-assemblies are
used in our custom designs. These include our own hybrids, qualified
for space. Semi- conductors and other parts are derated by at least
2:1 electrically and mechanically, and conservatively rated for
thermal and radiation stress.
Modular Design Benefits
Custom designs usually employ our standard modules. Many of these
contain our own thick and thin film proprietary hybrids, which we
build in quantities of thousands per year.
Reliability is increased, because large sections
of your unit have already been proven, not only by analysis but
actually in space.
Cost is less, because much of our design is pre-existing.
Delivery is faster, because we can eliminate considerable design
time. In some cases qualified components and modules are already
in stock, saving dollars as well.
