Allanson Transformers 2721-572 Transformer

The Allanson 2721-572 Ignition Transformer is a heavy-duty ferromagnetic solution engineered specifically for Nu-way Small Plate Burner applications. Providing a reliable 10,000Vac secondary voltage and 23mA current, this unit is designed to meet strict burner manufacturer specifications for consistent arc density. This model features a mid-point ground and is a direct replacement for 621620, as well as Webster 313-24AB82 and Thermolok C-807. Built with a single porcelain design and high-temperature wiring, it runs cooler and quieter than standard aftermarket units while offering superior EMI and RFI protection to prevent interference with sensitive boiler controls. This 120Vac supply voltage transformer is the primary choice for contractors requiring a high-voltage Allanson oil burner transformer that adheres to both American and European noise emission standards for residential and light industrial heating systems.

• Direct Cross-Reference: Identical to part number 621620 and 421-572 for seamless drop-in installation.
• Thermal Efficiency: Engineered to operate at lower temperatures, extending the life of the internal windings.
• EMI/RFI Suppression: Meets global standards to minimize electrical noise that can trip modern flame safeguards.
• Robust Construction: Utilizes high-temperature lead wires and porcelain insulators for high-arc resistance.

• Is this compatible with other burner brands? While designed for Nu-way Small Plate burners, it can replace units with matching 120V primary/10,000V secondary specs and plate dimensions.
• Does this include the mounting plate? Yes, this unit comes integrated with the specific small plate required for Nu-way housings.
• What is the grounding configuration? This is a mid-point ground transformer, ensuring balanced voltage across the electrodes.
