The single phase units are now
available in 100VA up to 25kVA ratings and input voltage ranges of 120 to 480V
ac. All units are encapsulated with electrical grade silica sand and resin
compounds to protect the core and coils, sealing out moisture and airborne
contaminants and eliminating corrosion and deterioration. The NEMA 3R
enclosures meet or exceed NEMA and ANSI standards for indoor and outdoor
applications, and are UL and CSA listed as well as CE approved. The Fortress series
encapsulated power transformers are backed with a 10-year limited warranty.
Prices start at $77.
With a better understanding of materials’ response to load and temperature, researchers could potentially use the knowledge to improve design. The research could even help geologists studying plate tectonics.
