    Control transformer
    Why do you use a 240v to 24v transformer in an air handler?

    To control secondary controls in the unit, most units require 24v control,, thermostat, limits, etc. What kind of air handler are you asking about, most air hanlders only require 120v, is this an electric furnace,, more info please.
