Buck-boost transformers

Buck-boost transformer designed to maximize and protect electrical equipment
By AutomationDirect  March 13, 2012

Buck-boost transformers are designed to maximize the performance and life of electrical equipment, such as air conditioners, heating elements, 277-V lighting systems, and in motors applications. Also called an isolation transformer, typical use is to power loads with specific voltage requirem ents, which differ from the available line voltage. 60Hz single-phase buck-boost transformers, with 50 VA to 2 kVA 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 quick and easy mounting.
