York S1-025-41034-000 Transformer

The York S1-025-41034-000 is a heavy-duty, OEM-spec 460V to 230V step-down transformer engineered for high-demand commercial HVAC applications. With a robust 150VA power rating, this component provides stable secondary voltage for control circuits, contactors, and relays within York and Johnson Controls equipment. The integrated spade terminals ensure a secure, low-resistance electrical connection, facilitating direct field installation without the need for proprietary harnesses or soldering. This unit is specifically built to handle the high inductive loads of larger commercial HVAC systems, maintaining precise voltage regulation even during peak operating compressor cycles. Designed as a direct-fit HVAC control transformer, it eliminates the need for field modifications or generic bracket adaptations often found with aftermarket alternatives. Technicians must verify primary line voltage and secondary VA load requirements to ensure the 150VA capacity matches the total draw of the connected logic boards and peripherals. Its industrial-grade construction is built to withstand the thermal stressors and high-frequency vibrations common in rooftop unit cabinets, making it the standard Johnson Controls replacement part for high-voltage control circuit isolation.

• Precise 460V to 230V conversion tailored for commercial power distribution.
• High 150VA capacity handles complex control strings and multiple contactor coils.
• Standard spade terminal configuration allows for rapid, tool-less wiring.
• OEM mounting footprint ensures compatibility with original York equipment frames.
• Engineered thermal dissipation to prevent nuisance tripping in high-ambient environments.

What is the primary input voltage for the York S1-025-41034-000?
This transformer is designed for a 460V primary input to step down power for 230V control circuits.

How do I install a 150VA 460V/230V transformer in a York RTU?
Ensure the power is disconnected, mount the unit using the existing bracket holes, and utilize the spade terminals to match the factory wiring schematic for high-voltage input and low-voltage output.

Is the York S1-025-41034-000 compatible with Johnson Controls systems?
Yes, as an OEM component, it is the direct replacement part for various Johnson Controls and York commercial air handling units requiring a 150VA rating.
