ZoneFirst T24 Transformer

The 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 directly onto junction boxes or within equipment cabinets. This HVAC step-down transformer is designed for continuous duty, ensuring a reliable power supply for residential and light commercial building automation. When sizing your control circuit, the T24 offers the headroom needed to prevent overheating in high-cycle environments. It is a drop-in solution for ZoneFirst control panels and other 24V peripheral devices requiring a dedicated transformer capacity for optimal performance and long-term field reliability.

• Consistent 40VA Power: Supplies ample current for multiple motorized dampers and 24V control logic.
• Robust Foot Mounting: Simplifies installation with a secure, vibration-resistant mounting configuration.
• Internal Protection: Engineered as a Class 2 power source to help prevent circuit damage and simplify wiring compliance.
• Broad Compatibility: Seamlessly integrates with ZoneFirst systems and all standard 24Vac residential HVAC components.

How many dampers can the ZoneFirst T24 handle?

Typically, a 40VA transformer can support 3 to 5 dampers, though you must verify the specific VA draw of your actuators to ensure the total load does not exceed 80% of the transformer's capacity.

Can I use this to replace a lower VA transformer?

Yes, replacing a 20VA or 30VA unit with the T24 is a common practice to provide more current headroom for the 24V secondary circuit, provided the output voltage remains the same.
