Description
The Allanson 2741-658 is an OEM ferromagnetic ignition transformer engineered to deliver dependable high-voltage spark energy for Beckett AF II oil burners and similar combustion systems. It operates on a 120 VAC primary and provides a 10,000 VAC secondary output with ~250 VA power and ~23 mA current, ensuring reliable ignition performance under constant-duty conditions. Built with high-temperature internal wiring, midpoint grounding, and a robust core, this transformer runs cooler and quieter while meeting EMI/RFI emission standards for compliant and long-lasting operation. It’s designed to meet burner manufacturer specifications and often replaces legacy references such as Webster 3-32AB-BAF.
