York S1-025-26312-700 Transformer

The York S1-025-26312-700 is an industrial-grade 500VA control power transformer designed for multi-tap primary configurations. Engineered for resilience in commercial HVACR environments, this unit handles primary voltages of 380V, 400V, and 416V, stepping them down to 115V or 230V secondary outputs. As a genuine York replacement part, it ensures precise voltage regulation and electromagnetic compatibility for sophisticated control circuits. The Step-Down Transformer S1-025-26312-700 features high-quality copper windings and robust insulation to withstand the thermal stresses of continuous duty cycles. For technicians troubleshooting York HVAC electrical components, this transformer provides the necessary VA capacity to power contactors, relays, and boards without voltage sag. Its versatile multi-tap design makes it a critical HVAC voltage regulator for international power standards and specific industrial sites requiring 400V to 115V conversion or 416V to 230V power supply setups.

• Multi-Tap Versatility: Supports primary inputs of 380, 400, and 416 volts for diverse site requirements.
• High VA Rating: 500VA capacity provides ample overhead for complex control strings and inductive loads.
• Dual Secondary Output: Configurable for 115V or 230V systems, offering flexibility for different control architectures.
• OEM Precision: Direct replacement ensures physical fitment and electrical parity with original York equipment.
• Thermal Stability: Built to maintain steady output under high-ambient conditions common in mechanical rooms.

Common Technical Questions

What are the wiring configurations for the different primary taps?
Wiring should follow the diagram on the transformer body to match the specific site voltage (380V, 400V, or 416V) to the correct primary leads, ensuring the desired 115V or 230V secondary output is maintained.

Is this transformer suitable for 50Hz and 60Hz applications?
Yes, this unit is engineered to operate effectively across common power frequencies, making it suitable for both domestic and international York chiller or AHU installations.

How do I verify if the 500VA capacity is sufficient for my control circuit?
Calculate the total inrush and steady-state volt-ampere requirements of all connected components; the 500VA rating provides a robust buffer for most standard commercial HVAC control loops.
