Buck-Boost Transformers

Buck-Boost transformers are small, single phase, dry type

distribution transformers designed and shipped as

insulating/isolating transformers. They have a dual voltage

primary and a dual voltage secondary. These transformers

can be connected for a wide range of voltage combinations.

The most common use is to buck (lower) or boost (raise) the

supply voltage a small amount, usually 5 to 27%. Buck-

Boost transformers are in compliance with NEC Article 210-9,

Exception 1 when field connected as an autotransformer.

The major advantages of Buck-boost transformers are their

low cost, compact size and light weight. They are also more

efficient and cost less than equivalent isolation transformers.

When connected as an autotransformer, they can handle

loads up to 20 times the nameplate rating. A buck-boost

transformer is the ideal solution for changing line voltage by

small amounts.

On this page:

When a buck-boost has the primary and secondary windings connected, per recommended instructions,

it becomes an autotransformer. Now only the secondary windings are transforming voltage and current.

The majority of the KVA load passes directly from the supply to the load. This is why buck-boost

transformers can supply a load with a much larger KVA rating than the nameplate indicates.

Ideal for low voltage lighting control applications

Sola/Hevi-Duty buck-boost transformers are designed to supply power to low voltage lighting circuits,

control panels or other systems requiring 12, 16, 24, 32, or 48 Volts. When connected as an insulating

transformer (by following the wiring diagram on the inside of the transformer case), the transformer's

capacity matches the nameplate KVA rating.

Sola/Hevi-Duty buck-boost transformers are also suited for low voltage landscape lighting. They are UL

listed for outdoor service and their compact size makes them the perfect solution for providing power to

accent lighting applications.

When using dimmers for low voltage applications, use only dimmers designed and rated for use with

magnetic loads. We strongly recommend contacting the dimmer manufacturer for advice on your

specific lighting application.
