AutomationDirect‘s power product line now includes buck-boost transformers from Jefferson Electric. Buck-boost transformers are designed to maximize the performance and life of electrical equipment, such as air conditioners, heating elements, 277-volt lighting systems, and in motors applications. Also called an isolation transformer, typical use is to power loads with specific voltage requirements, which differ from the available line voltage. Jefferson Electric 60Hz single-phase buck-boost transformers, with 50VA to 2kVA ratings, are encapsulated with electrical-grade resin, featuring high-quality electrical steel cores. The NEMA 3R-rated enclosures are heat-cured with an ASA-61 gray powder coat finish, and have slotted mounting holes for mounting. A buck-boost transformer can have two main applications. When connected as an auto-transformer, you can buck (lower) or boost (raise) available line voltage anywhere from five to 20 percent. When used as an isolation transformer, it can be used to step-down supply power to low-voltage circuits at the nameplate rating listed.
