The MT-BBT-208V-230V-20.8A 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, the MT-BBT-208V-230V-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-208V-230V-20.8A 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. 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-208V-230V-20.8A is designed to increase voltage from an input
voltage of 208 volts to an output voltage of 230 volts. The increase of voltage is
necessary when the on-site line-voltage is consistently lower 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-up transformer will allow equipment that draws up to
18.6 amps at 230 to be powered from 208 volt 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-up transformer can be either floor or wall mounted. The MT-BBT-208V-230V-
20.8A features a 130°C insulation with a 80°C temperature rise.

Construction:

The aluminum winding in the MT-BBT-208V-230V-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-208V-230V-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.

Benefits:

The MT-BBT-208V-230V-20.8A buck/boost step-up transformer offers

many benefits to the consumer. Buck/boost transformers pass the majority of the
load voltage directly through the transformer, only transforming a small
percentage of the load. Due to this technology, a smaller and quieter step-up
