Question: What are Combination / Multi tapped Transformers

Answer: In broad terms, a Combination Transformer is a single device that will take the place of two or more transformers or power supplies. A Combination Transformer may be a simple as a single phase single primary voltage (i.e., 480 volt, 60 Hz. input) with a dual secondary voltage output (i.e., secondary #1: 120 volts @ 500 VA; secondary #2: 240 volts @ 1 KVA), or as complex as a three phase multiple primary voltage device with multiple three phase isolation and auto-transformer outputs, multiple single phase outputs, and multiple DC voltage outputs.
