The main purpose of a buck-boost transformer the adjustment of incoming current to an appropriate level for operation of devices that require a specific voltage. Such items include motors, compressors, specialty lighting as well as any other applications in which a different voltage level than that provided by the main power line is necessary. Depending on the requirement, the transformer will either boost the power up to the necessary level or drop it down to suit low voltage needs, such as that of low voltage lighting.
