Low voltage is supplied by batteries or by a transformer that converts line voltage to a low voltage.

Low voltage wiring ac unit.

That brown sheathed low voltage wire from the air handler to the ac unit outside tells the contractor when to engage. The low voltage wire set will have two individual wire strands inside of an outer plastic sheathing. Common low voltages are 12v 24v and 48v. Protecting the low voltage wires to the ac.
