Modern Electronic Systems are increasingly being applied in outdoor, nonsheltered
or semi-sheltered environments. Special measures must be taken in the
design and construction of electronic assemblies in these environments to assure
optimal reliability. Power conversion equipment presents unique challenges
with this regard due to high electrical, thermal and vibration stresses, and the
large, irregular shaped components unique to their design.

TDI has developed several alternative equipment design and construction
techniques for highly reliable power conversion, compatible with increasing
environmental stress levels. The availability of this type of equipment opens up new
alternatives for system cost and reliability optimization.
