York S1-025-29056-000 Transformer

The York S1-025-29056-000 Transformer is a high-capacity 750VA control transformer designed for demanding commercial and industrial HVACR applications. Built for multi-tap versatility, this OEM York replacement part features a dual-voltage primary (240/480V) and a dual-voltage secondary (120/240V), providing technicians with the flexibility needed to match local utility service to internal control circuit requirements. With its robust 750VA rating, it handles the significant inrush currents associated with large contactors, relays, and auxiliary controls without secondary voltage sag.

Engineered for precision and thermal stability, the S1-025-29056-000 ensures consistent power delivery to sensitive electronic boards and ignition modules. This step-down transformer is a direct replacement for various York, Luxaire, and Coleman equipment, maintaining the integrity of the original system design. Its configuration is ideal for HVAC voltage conversion in packaged units and heat pumps where 480V three-phase power must be stepped down to 120V or 240V for control logic and fan motor circuits.

• Multi-Tap Input/Output: Supports 240/480V primary and 120/240V secondary configurations for maximum field adaptability.
• High Power Capacity: 750VA rating provides ample overhead for complex control strings and high-draw components.
• OEM Standards: Precise electrical specifications ensure seamless integration with York control systems and safety circuits.
• Thermal Reliability: Constructed with high-grade insulation materials to withstand the high ambient temperatures found in rooftop units and mechanical rooms.
• Stable Secondary Output: Minimizes voltage fluctuations, protecting sensitive microprocessors from electrical noise and undervoltage conditions.

What is the maximum current output for the 120V secondary?
At a 750VA rating, the 120V secondary provides up to 6.25 Amps, while the 240V secondary provides 3.125 Amps.

Can this transformer replace a lower VA rated unit?
Yes, a 750VA transformer can replace a unit with a lower VA rating (such as 300VA or 500VA) provided the physical dimensions fit and the primary/secondary voltages match.

Is this part compatible with non-York equipment?
While designed as a York OEM part, it is a universal 750VA industrial control transformer suitable for any application requiring 240/480V to 120/240V conversion.
