Sale price$428.48


The MT-BBT-230V-208V-20.8A Single Phase Step-Down Buck and Boost Transformer from Larson Electronics is powerful, reliable, and designed with the environment in mind. This transformer is designed to decrease 230 volts to 208 volts, and is needed when the line-voltage is lower than the required voltage for equipment. Suitable for both indoor and outdoor applications, the MT-BBT-230V-208V-20.8A provides increased reliability, higher efficiency, 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-230V-208V-20.8A buck and boost transformer is a single phase unit with a 4.326 kVA rating and a primary voltage of 230V AC using a maximum of 18.8 amps on the primary side. This step-down transformer has a secondary voltage of 208V and provides up to 20.8 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.

The MT-BBT-230V-208V-20.8A is designed to decrease voltage from an input voltage of 230 volts to an output voltage of 208 volts. The decrease of voltage is necessary when the on-site line-voltage is consistently higher than the voltage required by the equipment being operated or installed, preserving the lifespan of the equipment and guarantees correct operation without risking damage due to incorrect voltage. This step-down transformer will allow equipment that draws up to 20.8 amps at 208V to be powered from 230V power sources. Situations for this type of transformer may include lower voltage from your electrical provider or within the existing establishment, or operating equipment that requires a lower voltage than is provided at the existing establishment.

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. This step-down transformer can be wall mounted. The MT-BBT-230V-208V-20.8A features a 130°C insulation with a 80°C temperature rise.

Construction: The aluminum winding in the MT-BBT-230V-208V-20.8A are formed from high quality aluminum wire helps to improve performance. The close tolerances used during manufacturing also eliminate 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. The MT-BBT-230V-208V-20.8A is encapsulated in silica sand and resin, and cased in a NEMA 3R steel enclosure. NEMA 4, NEMA 4X, and NEMA 12 enclosures are available upon request.
