Brahma Ignition transformer 15911250

The Brahma Ignition Transformer 15911250 is a high-frequency electronic generator designed for ignition in gas and liquid fuel burners. It operates with a supply voltage of 220–240 V and a frequency of 50–60 Hz, delivering a secondary voltage of 15 kV and a secondary current of 45 mA. The transformer features a built-in short circuit protection, an integrated EMC filter, and a varistor for surge protection. It has a 100% duty cycle, weighs 0.42 kg, and is compatible with Brahma controllers. The recommended spark distance is 3–5 mm, and the maximum ignition cable length is 1.5 m.

When selecting an ignition transformer of this type, ensure the supply voltage, frequency, and output voltage match the burner's requirements. The transformer must be compatible with the controller and have the correct mounting configuration, such as M4x45 screws. Installation should be performed with the power off, and the valve body must be grounded. The transformer can be mounted in any position, and high-voltage cables should be kept away from other cables.

Common failures in ignition transformers include short circuits, open circuits, or insulation breakdown, leading to weak or no spark. Equipment may fail to ignite or exhibit intermittent ignition. Check for visible damage, measure secondary voltage and current, and verify the spark gap and cable integrity.
