Utica-Dunkirk 240001264 Transformer
The Utica-Dunkirk 240001264 Transformer is an essential OEM replacement component engineered for precision in residential and commercial hydronic heating systems. Specifically designed for compatibility with ECR International brands, including Utica, Dunkirk, and Pennco boilers, this step-down transformer converts high-voltage 208/230V primary input to a stable 24V secondary output. With a robust 40VA rating, it provides the necessary power for low-voltage control circuits, ensuring your thermostat, gas valves, and ignition modules receive reliable current without fluctuations.
For technicians in the field, this step-down control transformer offers a direct-drop-in fit, facilitating efficient diagnostic and repair cycles. Operating at 50/60Hz frequency, the 240001264 is built to withstand the thermal demands of boiler cabinets and indoor environmental stressors. When troubleshooting no-heat calls where 24V power is absent at the control board or contactor, replacing an aged or shorted unit with this genuine OEM part restores original system specifications and maintains the integrity of the total HVAC circuit.
Key Benefits:- OEM Precision: Genuine Utica-Dunkirk replacement part ensures exact electrical matching and mounting alignment.
- High VA Capacity: 40VA load rating supports advanced control boards and multiple low-voltage accessories.
- Voltage Stability: Maintains consistent 24V output to prevent chatter in contactors and potential damage to sensitive electronics.
- Broad Compatibility: Standardized for a wide range of ECR International hydronic equipment architectures.
- What causes a 24V transformer to fail? Failures are typically the result of a secondary-side short circuit, such as a pinched thermostat wire or a failing contactor coil, which overloads the windings.
- Can I use this for a 120V system? No, this is a 208/230V primary transformer. Connecting it to 120V will result in insufficient secondary voltage (approx. 12V), preventing the system from firing.
- How do I verify the secondary output? Use a multimeter to measure voltage across the secondary terminals; a healthy unit should read between 24V and 28V AC under no-load conditions.
