York S1-025-33469-000 Transformer

Ensure reliable control circuit performance with the York S1-025-33469-000 Transformer, a heavy-duty industrial component engineered for precision step-down voltage conversion in commercial HVACR equipment. This multi-tap primary transformer supports 208V, 240V, and 480V power inputs, providing a stable 24V secondary output to drive thermostats, control boards, and contactors. With a 75VA power rating, it offers significantly more overhead than standard 40VA units, making it the preferred choice for systems with high-draw solenoid valves or complex relay logic. As a genuine York OEM replacement part, this Class 2 transformer features foot-mount installation for secure chassis placement and color-coded leads to streamline HVAC transformer wiring. Designed to withstand the thermal stress of continuous operation at 50/60Hz, the S1-025-33469-000 maintains high efficiency and minimizes inductive noise, ensuring long-term stability for critical low-voltage HVAC control systems and industrial automation panels.

• Universal Primary Voltage: Supports 208/240/480VAC inputs, allowing a single part to cover multiple field service applications.
• 75VA Capacity: High volt-ampere rating ensures sufficient current for modern, high-load HVAC controls and multi-stage systems.
• OEM Compatibility: Exact fit for specific York, Coleman, and Luxaire air handlers and rooftop units, eliminating the need for mounting modifications.
• Industrial Build Quality: Robust resin-encapsulated coils provide superior moisture resistance and heat dissipation in demanding mechanical rooms.

Is the S1-025-33469-000 compatible with 480V 3-phase systems?
Yes, the primary side of this transformer includes a 480V tap. For 480V applications, use the white (common) and red (480V) primary leads while ensuring any unused taps are safely capped.

What happens if I replace a 40VA transformer with this 75VA model?
Upgrading to a 75VA rating is generally recommended, as it provides a higher current threshold (approximately 3.125 Amps at 24V), preventing the transformer from overheating under heavy control loads.

Can this transformer be used for both 50Hz and 60Hz frequency applications?
Yes, this component is rated for 50/60Hz operation, making it suitable for both domestic and international power standards in commercial HVACR environments.
