AutomationDirect (Cumming, GA) has expanded its Hammond line of HPS Fortress commercial encapsulated power transformers. The single-phase units are now available in 100VA to 25kVA ratings and input voltages ranges of 120VAC to 480VAC. They are encapsulated with electrical-grade silica sand and resin compounds to protect the core and coils, which seals out moisture and airborne contaminants. In addition, the NEMA 3R enclosures meet or exceed NEMA and ANSI standards, which includes resistance to corrosion and deterioration.
