Allanson Transformers 2721-630 Transformer

The Allanson 2721-630 ignition transformer is a high-performance electrical component engineered specifically for heavy-duty oil burner applications. Operating on a 120Vac supply voltage, this unit delivers a consistent 10,000Vac secondary voltage at 23mA, ensuring reliable arc stabilization for efficient combustion. Designed with a midpoint ground, it effectively manages electrical noise and spikes, protecting sensitive burner controls. This transformer serves as the precise direct replacement for the Allanson 28219 and is the standard technical specification for Carlin 99 and 100 CRD burners. Its robust internal windings are vacuum-impregnated to withstand the high thermal demands of industrial heating environments. Whether you are performing a routine service or a critical repair, utilizing the Allanson 2721-630 oil burner transformer ensures the ignition system meets original equipment manufacturer (OEM) standards for strike voltage and sustained spark gap performance.

Key Benefits:

• Direct OEM Compatibility: Engineered as a drop-in replacement for 28219, reducing field modification time during installation.
• Optimized Ignition Output: Provides a 10kV secondary voltage to ensure rapid flame propagation in high-static pressure burners.
• Industrial Durability: Built to handle the rigorous duty cycles of Carlin 100 CRD models without dielectric breakdown.
• Moisture Resistance: Encapsulated design prevents tracking and shorts caused by environmental humidity or oil residue.

Common Questions:

What is the primary difference between the 2721-630 and the 28219?
The 2721-630 is the updated technical equivalent and direct successor to the 28219, maintaining identical mounting footprints and electrical output ratings.

Can this transformer be used on other Carlin models?
While specifically spec'd for the Carlin 99 and 100 CRD, it may fit other oil burner ignition systems requiring a 10kV midpoint ground output; always verify mounting bracket dimensions before installation.

Does a 23mA rating affect electronic primary controls?
No, this 23mA output is matched to standard industrial primary controls, providing sufficient current for the arc without overloading the control circuit.
