The Allanson 444-BT636 is a professional-grade ferromagnetic service replacement transformer engineered for demanding oil burner applications. Operating on a 240Vac supply voltage, this unit delivers a consistent 10,000Vac secondary voltage at 23mA, utilizing a mid-point ground configuration. As a veteran in the field, you know the value of the "Universal" designation; this model features six-position adaptability and includes a universal base plate to simplify field retrofits and reduce the need for carrying multiple SKUs on your service truck. Designed with high-temperature lead wires and a robust internal primary wiring compartment, it ensures reliable ignition transformer performance even in high-heat environments. This 250VA rated component meets stringent EMI and RFI noise emission standards, providing superior protection for sensitive electronic burner controls. Whether you are servicing residential boilers or industrial grain dryers, the Allanson 444-BT636 provides the secondary output stability required for clean, efficient combustion.

• Universal Compatibility: Includes six-position adaptable mounting and a base plate to replace a wide range of OEM burner transformers.
• High-Voltage Stability: Delivers a reliable 10kV arc for consistent electrode firing in various oil-fired applications.
• Electrical Protection: Engineered to meet American and European standards for minimal radio frequency interference (RFI).
• Refined Durability: Construction features high-temperature wiring and single porcelain designs for extended service life in harsh conditions.

Can I use the 444-BT636 to replace a 120V transformer?
No. This unit is specifically rated for 240V primary input. For 120V applications, you must use the equivalent Allanson 421 series model.

What does 'Mid Point Ground' mean for my installation?
The mid-point ground design splits the 10,000V secondary across two terminals relative to the ground. Ensure your burner leads are properly isolated and your ground connection is secure to prevent housing arc-over.

Does this include the base plate?
Yes, this universal model is supplied with a multi-hole base plate to accommodate various burner housing footprints.
