Grand Canyon 12–24V Transformer (620-402)

The Grand Canyon 620-402 Transformer 12–24V is a replacement low-voltage power transformer used with compatible Grand Canyon control systems and electronic ignition components. Designed to step incoming line voltage down to a 12–24V operating range, this transformer supplies the control power required for select ignition modules, valves, or Weather Beater/EIS-style systems. It is intended as a service part when the original transformer fails or is damaged, allowing a technician to restore proper low-voltage power delivery without replacing the entire control package.
