Description
The Allanson 421-664 is a robust OEM ferromagnetic ignition transformer engineered to deliver dependable high-voltage spark energy for Webster Engineering oil burner systems and similar HVAC combustion applications. It runs on 120 VAC primary power and steps up to 10,000 VAC secondary output with ~23 mA current at ~250 VA, providing strong and consistent ignition performance under constant duty. Designed with high-temperature internal wiring and a midpoint-grounded double-pole core, this transformer runs cooler and quieter than many generic units and complies with American and European EMI/RFI noise emission standards for safer, long-lasting operation. The single porcelain design and compact construction make it a dependable choice for residential, commercial, and industrial oil burner ignition systems.
