Johnson Controls Y65T31-0 Transformer While typically used to setProfessional grade Johnson Controls Y65T31 0 Transformer is a critical component for technicians managing multifaceted HVACR control systems. As a 40VA Class 2 control transformer, this unit is engineered to step down multi tap primary voltages of 120V, 208V, or 240V to a reliable 24V secondary output. The split bobbin design ensures superior primary to secondary isolation, minimizing the risk of noise interference in sensitive digital controllers and
