Description
The Johnson Controls Y64T21-0 is a plate mount control transformer. It is a device that safely transforms incoming high voltage AC electricity of 120/208/240V to a lower voltage of 24V suitable for controlling low voltage circuits in HVAC systems. This lower voltage tends to minimize the risk of electric shock and this helps the technicians working on the equipment. This is the type often described as dry transformer where the heat dissipation in the core is made through circulation of air. It is specifically for plate use so that it can be mounted easily in electrical panels or enclosures.
