This is an ignition transformer specially designed for combustion appliances, manufactured by LECIP Japan. It converts 100/200V AC input into 10kV high voltage to generate ignition spark for fuel oil burners of marine boilers. The fully epoxy-potted metal housing provides excellent protection against oil mist, humidity and salt fog in engine rooms. Dual voltage input is compatible with both 110V and 220V marine power grids. The midpoint grounded secondary winding improves anti-explosion safety, and two ceramic high-voltage terminals resist long-term arc ablation. Widely used as original spare parts for marine auxiliary steam boilers and hot water heating boilers.
