ALLANSON FERROMAGNETIC SERVICE REPLACEMENT TRANSFORMER

Description

The Allanson Ferromagnetic Service Replacement Transformer, exemplified by models like the 421 series such as 421-664, is a robust double-pole ignition transformer engineered for constant-duty operation in demanding commercial, residential, and industrial oil burner applications. It delivers a reliable high-voltage ignition source with 120V input supply (108-132V operating range), 60Hz frequency, and 250VA primary rating, stepping up to 10,000V RMS secondary voltage at 23mA short-circuit current. Constructed with high-temperature wire and single porcelain designs, it ensures cooler, quieter, and safer performance across all burner types while meeting American and European noise emission standards for superior EMI/RFI protection. 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. Mounting features 1/4-20 x 1-inch studs with primary three-wire configuration and ground wire. In visual communications, signage, and printing industries, this transformer supports neon and cold cathode lighting systems requiring stable high-voltage power for illuminated displays and architectural signage, offering dependable service replacement with proven reliability to burner and lighting manufacturer specifications. Its durable build minimizes downtime, making it ideal for B2B maintenance and upgrades in high-reliability display installations.
