ALLANSON FERROMAGNETIC TRANSFORMER

Description

The Allanson Ferromagnetic Ignition Transformer, exemplified by models like the 421-664, is a high-performance double-pole unit engineered for constant-duty operation in commercial, residential, and industrial oil burner applications. It delivers reliable ignition through a robust secondary voltage of 10,000V RMS at 23mA short circuit current, with a 120V AC input (108-132V operating range) at 60Hz and 250VA primary rating. Constructed with high-temperature wire for enhanced durability, it operates quietly and safely across diverse burner types, meeting manufacturer specifications for proven reliability. Key specifications include storage temperatures from -40°C to +80°C, operating temperatures from -30°C to +40°C at 90% relative humidity, and a loading air gap of 1/8 to 3/16 inches. Single-pole variants, such as the 542-A-SF, support gas applications with similar cooler-running designs. While primarily optimized for heating and HVAC ignition in burner systems, these transformers offer potential integration in visual communications and signage setups requiring stable high-voltage spark sources for neon or specialized lighting effects. Their rugged construction ensures long-term performance in demanding environments, making them ideal for B2B procurement in precision electrical applications.
