Allanson Transformers 421-430 Gas Transformer

Allanson Transformers 421-430 Gas Transformer delivers reliable high-voltage performance for demanding ignition and control circuits. This gas transformer features a 250 V AC primary and 10000 V AC secondary, operating at 60 Hz to power ignition modules in gas furnaces across residential, commercial, and industrial settings.

Built around a ferromagnetic core with a mid-point ground, the two-pole design provides solid performance in challenging environments. Zinc-plated button terminals ensure durable connections, while a 120 V AC rating keeps it compatible with common power systems.

Engineered for broad temperature and humidity tolerance, it withstands storage from -40 to 80 C and operating conditions from -30 to 40 C, with up to 90% relative humidity. It is ideal for gas furnace applications where reliable isolation and ignition timing are essential.
