York S1-026-38070-006 Transformer
This York S1-026-38070-006 Transformer is a heavy-duty 480V to 24V step-down transformer engineered specifically for commercial HVACR applications. As an OEM York replacement part, it ensures seamless integration with factory control circuits, eliminating the guesswork often associated with universal alternatives. With a robust 100VA power rating, this component provides ample overhead for driving multiple low-voltage loads, including high-draw contactors, relays, and advanced microprocessor control boards. The primary 480V winding is designed to handle industrial line voltages, while the 24V secondary output maintains a stable control signal to prevent chatter or erratic system behavior. For technicians in the field, this HVAC control transformer features standard mounting foot dimensions and clearly identified leads to expedite installation on rooftop units and chillers. Utilizing original Source 1 parts like the S1-026-38070-006 ensures the electrical integrity of the system is maintained according to manufacturer specifications, reducing the risk of premature component failure in high-demand environments.
Key Benefits- High Power Capacity: The 100VA rating provides superior current handling for complex commercial control strings compared to standard 40VA or 75VA units.
- Precision Step-Down: Specifically wound to convert 480V primary input to a consistent 24V secondary output, protecting sensitive electronics.
- OEM Compatibility: Exact drop-in York replacement part ensures mounting holes and wiring configurations align perfectly with existing equipment.
- Industrial Durability: Built to withstand the thermal stressors common in outdoor condenser sections and mechanical rooms.
Can I use this 100VA transformer if my old one was only 75VA?
Yes. In HVAC applications, you can increase the VA rating (capacity) without issue. The 100VA rating simply means this transformer can handle a larger electrical load, providing a more robust power supply for your controls.
What causes a 480V transformer to fail prematurely?
Most failures are caused by downstream shorts in the 24V circuit, such as a grounded contactor coil or a pinched thermostat wire. Always check for shorts before energizing the new S1-026-38070-006.
Is this transformer multi-tap for different primary voltages?
This specific model is optimized for 480V primary applications. Always verify your incoming line voltage with a multimeter before installation to ensure it matches the 480V requirement.
