Brahma Ignition transformer TC2LTCA 15911107

The Brahma Ignition transformer TC2LTCA 15911107 is a compact, high-frequency electronic ignition transformer designed for gas and liquid fuel burners. It operates on a supply voltage of 220–240 V at 50–60 Hz, delivering a secondary voltage of 24 kV and a secondary current of 55 mA. The transformer features a built-in short-circuit protection and varistor protection, and it can be supplied with an integrated EMC filter to comply with directive 2004/108/EC without external filters. It has a duty cycle of 100%, a net weight of 0.42 kg, and supports an ignition cable length up to 1.5 m with a standard power cable length of 560 mm. The recommended spark distance is 3–5 mm, and the output voltage frequency ranges from 6 to 10 kHz. The unit has 2 contacts and is available with single or double high-voltage output, various mounting and connecting systems, and is compatible with Brahma controllers.

When selecting a replacement ignition transformer of this type, ensure the supply voltage, frequency, and secondary voltage/current ratings match the burner's requirements. Check the mounting dimensions and connection types (e.g., threaded or connector for high voltage, and power cable or connector) to fit the existing setup. The transformer must be compatible with the burner's controller, and the ignition cable length should not exceed the specified maximum. Verify the spark distance and duty cycle to match the application's operational demands.

Common failures of ignition transformers include internal short circuits, open circuits, or breakdown of insulation, leading to weak or no spark. Symptoms may include the burner failing to ignite, intermittent ignition, or visible arcing or damage to the transformer casing. Check for proper supply voltage, continuity of the high-voltage cable, and signs of overheating or physical damage. If the transformer has a built-in filter, ensure it is not faulty, as this can cause electromagnetic interference issues.
