Description
The Johnson Controls Y66T12-0 is a control transformer that is used to safely step up higher voltage 120, 208 or 240 VAC down to a lower voltage 24 VAC that is used to power control circuits in HVAC systems and other industrial applications. This is a small and efficient transformer with a foot mount that makes it easy to install and has a robust construction to last long. Internally the transformer uses electromagnetic induction to reduce the voltage that is available at the transformer terminals. The Y66T12-0 model has a 75VA rating and can be used in many control applications. The following are the advantages that this transformer brings to HVAC systems.
