Product Description

The MT-BBT-208V-240V-62.5A Single Phase Energy Efficient Buck and Boost 50/60Hz Transformer from Larson Electronics is powerful, reliable and designed with the environment in mind. Suitable for both indoor and outdoor applications, the MT-BBT-208V-240V-62.5A provides increased reliability, protection against critical equipment failures and an extra level of protection by isolating the power source from the connected device. The lower operating costs, lower heat emissions and lower cost of ownership make this transformer ideal for a wide range of applications and businesses.

Transformer Features: The MT-BBT-208V-240V-62.5A buck and boost transformer is a single phase unit with a 14.75kVA rating and a primary voltage of 208V AC with 70.8 amps available on the primary side. It also provides a secondary voltage of 240V and has 62.5 amps available on the secondary side. Featuring robust construction, this unit`s cores are manufactured with non-aging, cold-rolled silicon steel laminations using state of the art technology.

This unit boasts a low cost of ownership and is highly energy efficient. Lower heat emissions mean less cooling is needed as well. The NEMA 3R painted steel enclosure makes the unit suitable for both indoor and outdoor applications and it can be either floor or wall mounted. The unit features a 180°C insulation with a 115°C temperature rise.

Benefits: The MT-BBT-208V-240V-62.5A buck and boost transformer offers many benefits to the consumer. Precision cut copper transformer winding material help to improve performance. The close tolerances used during manufacturing also eliminates burrs which hinder performance. Each core is specially coated to prevent the ingress of moisture and are electrically balanced to minimize axial forces during short circuit situations. Buck and boost transformers are designed to maximize the performance and life of electrical equipment.

This transformer provides owners with significant energy savings as well as offering environmental benefits. Higher efficiency not only extends the life of the transformer, but also turn into cost savings for owners in the form of lower energy bills and decreased cost of ownership. Integrated wall mounting brackets make installation fast and easy.

Applications: Air conditioners, lighting systems, heating elements, motor applications and other applications that that require the ability to power loads that differ from the available line voltage.

Larson Electronics is a manufacturer and as such can build stationary and portable transformer systems to your specifications. Although we carry several models of power distribution transformer systems, we can deliver custom ordered units almost as quickly as our prebuilt units. If this model does not meet your needs, please get in touch with us to discuss your specific requirements.

Larson Electronics Buck Boost Transformer FAQ

Frequently Asked Questions (FAQ) - Larson Electronics MT-BBT Series

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 autotransformer 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 field 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 autotransformer. The primary and secondary windings are no longer isolated as they are connected together.
