Space Environmental Test Facility (SETF)
This unique 23,000 sq. ft. test facility supports the power electronics environmental testing of current programs, i.e. ISS, RS-68 and KEW for thermal and vibration testing. Future plans are to support commercial programs, including satellite power and engine controllers.
- 12 thermal vacuum chambers
- 5 thermal chambers
- 2 vibration stations
- 5000 sq. ft. manufacturing assembly support facility
 Space Power Electronics Lab (SPEL)
This 10,000 sq. ft. facility with 6,400 sq. ft shield is the most unique power laboratory in the world. It provides a powerful test bed for full performance end-to-end testing.
SPEL has been operational since 1989 and
is ready and capable of any DC & AC high voltage power electronics testing. The test and measurement capabilities in SPEL includes power output, no-load to full load, efficiency, power quality, power stability, worst case performance, fault tolerance and recovery, voltage and current transfer function, ripple and noise measurement, end-to-end communication and control algorithms, full system integration and evaluation, power system firmware evaluation, step load control and system stability measurement.
SPEL was a major contributor to the International Space Station Power System Integration and Test Program.
