York S1-025-30867-001 Transformer

The York S1-025-30867-001 Transformer is a heavy-duty step-down component engineered for industrial and commercial HVAC applications requiring precise voltage regulation. This genuine OEM part features a multi-tap 460/575V primary input and a stable 230V secondary output, rated at 165VA. Designed to handle high-demand electrical loads, it ensures that your system's control circuits and auxiliary components receive consistent power, preventing fluctuations that can lead to premature hardware failure in heavy equipment. The robust construction and 60Hz frequency compatibility make it a primary choice for technicians servicing York rooftop units and chillers.

When swapping out an aging or shorted transformer, the S1-025-30867-001 offers a direct drop-in replacement, facilitating clear terminal identification for streamlined wiring. Its industrial-grade insulation and coil design are optimized for high-temperature environments typical of mechanical rooms and outdoor penthouses. Utilizing this 165VA control transformer ensures that secondary components, such as contactors and fan motors, operate within their specified electrical parameters, maintaining the integrity of the total HVAC system architecture.

Key Benefits:

• Compatible with high-voltage 460V and 575V primary circuits common in industrial facilities.
• Provides a dedicated 230V secondary power supply for sensitive control components.
• High 165VA capacity accommodates multiple auxiliary loads without voltage drop.
• Original York OEM replacement part ensures precise chassis fit and terminal alignment.
• Constructed with high-grade electrical steel and windings for maximum efficiency and thermal stability.

Common Questions:

Can I use this transformer on a 575V 3-phase system?
Yes, the York S1-025-30867-001 is specifically designed with a 575V primary tap to accommodate standard Canadian and industrial power grids.

What symptom indicates this transformer has failed?
Common indicators include a lack of 230V secondary output, a burnt smell near the windings, or a tripped primary breaker. Always verify input voltage before assuming a transformer failure.

Does this part replace discontinued York transformer models?
This part is the current standard for several legacy York part numbers. Always cross-reference your specific model number, such as DJ150N15P4AAA3A or F2FP048H06, to ensure the 165VA rating meets your secondary load requirements.
