Supco SXT105 Transformer
The Supco SXT105 Transformer is a heavy-duty, 40VA HVAC control transformer designed for multi-tap field flexibility. Engineered as a foot mount transformer, this unit offers high compatibility for technicians servicing residential and light commercial equipment. It features a triple-tap primary for 120V/208V/240V configurations and a consistent 24V secondary output, making it the industry-standard direct replacement for 4031F and various Honeywell or White-Rodgers models. Its Class 2 rating ensures safe integration into furnace control boards, thermostats, and zoning systems. For contractors, the SXT105 simplifies truck stock by replacing multiple single-voltage SKUs with one reliable 50/60Hz component. The robust construction handles the inductive inrush of contactors and relays without premature core saturation, maintaining stable voltage across the low-voltage circuit.
Key Benefits- Universal Compatibility: Serves as a versatile 24V step-down transformer for systems requiring 40VA or lower capacity.
- Multi-Tap Primary: Supports 120/208/240V primary voltage, allowing for standard furnace, heat pump, or commercial power tie-ins.
- Simplified Installation: The foot mount design matches standard HVAC chassis footprints for quick field swap-outs.
- Broad OEM Cross-Reference: Replaces models like the Honeywell AT40A series and Mars 50354, reducing downtime.
Can I use the SXT105 to replace a 30VA transformer?
Yes, this 40VA transformer can replace units with equal or lower VA ratings, provided the primary and secondary voltages match your system requirements.
Is this unit rated for both heating and cooling applications?
This is an HVAC/R control transformer suitable for air conditioning circuits, gas valves, and heating relays optimized for 24VAC control systems.
Does it include an internal circuit breaker?
The SXT105 is a standard Class 2 model without an integrated manual-reset breaker; ensure your circuit includes external fusing if required by local codes.
