BUCK-BOOST TRANSFORMERS
Buck-Boost Transformers offer a no-frills approach to low voltage lighting. (See Chart Below) A typical Buck-Boost application is 120
volts in and 12 volts out for low voltage lighting or control circuitry. In most applications, this low voltage isolation transformer is field
connected as an autotransformer. For more information on Buck-Boost Transformers, refer to the next section in this catalog.
