Designed for stable voltage adjustment without regulation, it offers customizable options and is built with safety as a priority, making it ideal for professional industrial and commercial applications. ## Description (Q) What are Buck‐Boost Transformers and where are they used? A) Buck-boost transformers are potted transformers with low voltage secondary windings. By field connecting the primary and secondary windings in an auto-transformer configuration (not isolated), they offer an economical solution to the adjustment of line voltages that are slightly above or below normal. These transformers should be used to adjust stable voltages only. Q) Can a Buck-Boost Transformer regulate the output voltage? A) No. A buck-boost transformer will not regulate the voltage. If the input voltage varies, then the output voltage will also vary by the same percentage. The output (or secondary voltage) of a buck-boost transformer is dependent on the primary voltage and the transformer turns ratio. Therefore, fluctuations in the secondary voltage are direct results of any fluctuations in the primary voltage. We do offer voltage regulators. Q) Will a Buck-Boost Transformer create a neutral on the output? My application requires a neutral. A) No. A buck-boost transformer will not derive a neutral. If your application requires a neutral and you do not already have a neutral, you will require an isolation transformer. Neither single phase or three phase buck-boost transformers will create a neutral. Q) Will a Buck-Boost Transformer output even voltage on both output legs? A) No. Our standard buck-boost transformers do not generate even legs. For single phase applications, we do offer a line of buck-boost transformers that will output even legs. Three phase units will not output even legs. If you require even legs on the output voltage, we recommend purchasing an isolation transformer and not a buck-boost transformer. Q) How does a buck‐boost transformer differ from an isolating transformer? A) A Buck-Boost transformer is manufactured as an isolating transformer, with separate primary and secondary windings and is shipped from the factory in that configuration. When fields are connected for a buck-boost application, the primary and secondary windings are wired together which changes the transformer’s electrical characteristics to those of an auto-transformer. The primary and secondary windings are no longer isolated as they are connected. ## Features - Contact us today for information about custom options tailored to meet your specific needs - For safety reasons, we cannot accept returns on transformers, phase or frequency converters. - Once these products leave the factory, they cannot be resold and must be destroyed to ensure every unit sold is safe to use. ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B09GWCC5BH | | Best Sellers Rank | #699,992 in Industrial & Scientific (See Top 100 in Industrial & Scientific) #228 in Isolation Transformers | | Brand Name | Larson Electronics | | Current Rating | 35.4 A | | Customer Reviews | 5.0 5.0 out of 5 stars (3) 5.0 out of 5 stars | | Item Weight | 35 pounds | | Manufacturer | Larson Electronics LLC | | Maximum Frequency | 60 hertz | | Minimum Frequency | 60 hertz | | Model | 153242 | | Mounting Type | Floor Mount or Wall Mount | | Number Of Items | 1 | | Part Number | 153242 | | Specification Met | NEMA | ## Images ![- 1-Phase Buck/Boost Step-Down Transformer - 240V Primary - 208V Secondary -35.4, 60 or 130 Amps -50/60Hz - Image 1](https://m.media-amazon.com/images/I/61SaS+dCusL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Transform your world *by on Reviewed in the United States March 21, 2025* Saved my butt!
