Jefferson Electric Buck-Boost Transformers, Auto-Transformers and Isolation Transformers
Buck-boost transformers are designed to maximize the performance and life of electrical equipment. They are typically used to power loads with specific voltage requirements that differ from the available line voltage. A single buck-boost transformer is used to boost or buck single-phase voltage. Two or three units are required to boost or buck three-phase voltage. Buck-boost transformers can be connected as auto-transformers or isolated transformers.
When connected as an auto-transformer, these buck-boost transformers provide a means of raising (boosting) or lowering (bucking) a supply line voltage by a small amount (usually no more than 20 percent).
When connected as an isolation transformer, these power transformers can be used to step-down supply power to low voltage circuits at the nameplate rating listed.

Welcome to Kick-start where you get to see new products here at AutomationDirect. Well today, I'm going to show you our new Buck Boost Transformers by Jefferson electric we offer 17 sizes ranging from 50 Va up to 2,000 va now these Buckley's transformers are single-Phase. But can be used in a three-Phase open Delta with the use of two transformers and can be used in the three-Phase y application with the use of three transformers and we have these in 240 by 120 V Ac primary and 24 by 12 V Ac secondary and 240 by 120 V Ac primary and 32 by 16 V Ac secondary if you want to know what the difference is in a standard Transformer versus a buck boost transformer. I'll try to give a quick explanation Standard Transformers Hendel large increases and decreases in voltage and provide electrical isolation. Or is a buck boost transformer handles small increases and decreases and do not provide electrical isolation and will not compensate. For fluctuation source voltage they're designed to maximize the performance and the life of electrical equipment Buck Boost Transformers are also known as auto Transformers now applications for Buck boost Transformers include air conditioners heating elements motor applications 277-volt supply for lighting systems and more. Now you can find the agency approvals and the specs for these bug boost transformers on our website at automationdirect.com Don't forget we sell control and encapsulated transformers as well as other electrical power products. Check back with us often on AutomationDirect websites or on youtube.com/automationdirect for more Kickstart videos and if you’re watching with us today on YouTube. Please, let us know what you think about this transformer or how you plan to use it in your next application By dropping us a comment down below Thanks for watching and we hope to see you again soon.
