Description
The Allanson 421-430 is a durable OEM ferromagnetic ignition transformer designed to provide reliable high-voltage spark energy for Ducane oil burner systems and other HVAC combustion applications. It accepts a 120 VAC primary input and steps up to a 10,000 VAC secondary output with ~23 mA current and ~250 VA rating, delivering consistent ignition performance under continuous duty. Built with high-temperature internal wiring, midpoint-grounded double-pole construction, and designed to burner manufacturer specifications, this transformer operates cooler and quieter while meeting EMI/RFI noise emission standards.
