Description
The Allanson 2721-628G is a reliable OEM ferromagnetic ignition transformer designed to produce high-voltage spark energy for Beckett A, AF, and AFG oil burner systems. It runs on 120 VAC primary power and delivers 10,000 VAC secondary output at ~23 mA with a ~250 VA rating for consistent ignition performance under constant duty. Built with high-temperature internal wiring and a midpoint-grounded core, this transformer operates cooler and quieter than generic units while meeting EMI/RFI noise suppression standards for safer, long-term operation. Its compact “small can” form factor and standard end-hinge mounting ensure broad compatibility with oil burners and HVAC combustion controls.
