This single phase step-up Buck and Boost Transformer from Larson Electronics is powerful, reliable, and designed with the environment in mind. This transformer is designed to increase 208 volts to 230 volts, and is needed when the line-voltage is lower than the required voltage for equipment. Suitable for both indoor and outdoor applications, providing increased reliability, higher efficiency, protection against critical equipment failures and an extra level of protection by isolating the power source from the connected device.

Transformer Features: This buck and boost transformer is a single phase unit with a 4.77 KVA rating and a primary voltage of 208 VAC using a maximum of 20 amps on the primary side. This step-up transformer has a secondary voltage of 230 V and provides up to 18.6 amps available on the secondary side. This is designed to increase voltage from an input voltage of 208 volts to an output voltage of 230 volts. This step-up transformer will allow equipment that draws up to 18.6 amps at 230 to be powered from 208 volt power sources.

Mounting: Integrated wall mounting brackets make installation fast and easy.

Custom Builds: Although we carry several models of power distribution transformer systems, we can deliver custom ordered units almost as quickly as our pre-built units. If this model does not meet your needs, please notify us to discuss your specific requirements.

Larson Electronics Buck Boost Transformer FAQ

(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.
