Description
The Allanson 421-BT636 is a universal ferromagnetic ignition transformer engineered for robust high-voltage spark energy in multi-burner oil burner and HVAC combustion applications. It runs on a 120 VAC primary input and delivers 10,000 VAC secondary output at ~23 mA (~250 VA), providing consistent ignition performance under constant duty. This universal service replacement features six-position adaptability, a midpoint-grounded double-pole core, and high-temperature internal wiring for cooler, quieter, and reliable operation. It’s designed to meet burner manufacturer specifications and replace common legacy parts like Webster 312-25AX0600, France LAUV, and T-628 series.
