ALLANSON 2742-500 IGNITION TRANSFORMER

Description

The ALLANSON 2742-500 Ignition Transformer is a double pole ferromagnetic transformer engineered for constant duty, delivering the most reliable ignition source in demanding commercial, residential, and industrial oil burner applications. Operating at 220-240 Volts, 50/60 Hz, it produces a 12,000 Volt peak secondary output at 20 mA with mid-point ground configuration, ensuring stable spark performance across a wide temperature range of -40°C to +80°C ambient and -30°C to +40°C coil ratings. Key specifications include a compact 1.14-inch height, 90-degree rotation capability, and compatibility with 1/8 to 3/16-inch electrode gaps, supporting 250-hour minimum life at 50% duty cycle. Constructed with durable, fire-retardant materials for enhanced safety and longevity, it features robust high-voltage terminals and mounting options suited for integration into HVAC and combustion systems. While primarily designed for oil ignition in heating and HVAC electrics, its high-reliability design offers potential adaptability for specialized visual communications equipment requiring precise, high-voltage sparking, such as custom signage fabrication or printing process igniters. This transformer exemplifies Allanson's 90+ years of expertise in power conversion, providing consistent performance and easy replacement in field installations.
