Description
The Allanson 421-659 is an OEM ferromagnetic ignition transformer designed to deliver reliable high-voltage spark energy for Cleaver Brooks, Industrial Combustion, and similar burner systems. It operates on 120 VAC primary power and steps up to 10,000 VAC secondary output with approximately 23 mA and ~250 VA, providing consistent ignition performance for residential, commercial, and industrial HVAC applications. Built to meet burner manufacturer specifications, this transformer features high-temperature internal wiring and a midpoint-grounded double-pole core, which helps it run cool and quieter under continuous duty while complying with EMI/RFI noise emission standards.
