ZoneFirst T24 Transformer For steam applications up toThe ZoneFirst T24 Transformer is a critical component for powering modern HVAC zoning systems, engineered to convert 120Vac input voltage to a consistent 24Vac secondary voltage. With a 40VA rating, this Class 2 transformer provides the necessary amperage to drive multiple damper actuators and control boards without the risk of voltage sag under load. Technicians will appreciate the robust foot mount design, which allows for stable installation
