Allanson Transformers 2721-411 Gas Transformer

Allanson 2721-411 Gas Transformer delivers reliable high-voltage performance for gas furnace systems. The Allanson 2721-411 Gas Transformer converts 250V AC input to 10,000V AC output, making it an essential high voltage transformer for residential, industrial, and commercial gas furnaces.

Built with a ferromagnetic core and a mid-point ground configuration, this dual-pole gas transformer is designed for durable operation in demanding environments. It handles a 60 Hz frequency, supports a 120V AC line, and provides a stable ignition signal for efficient furnace performance. It is rugged, compact, and designed for long service life in both new builds and replacements. The end hinge design simplifies mounting, and zinc-plated button terminals resist corrosion in commercial installations.
