Brahma Ignition transformer TC1LTCAF 15910407

The Brahma TC1LTCAF ignition transformer (SKU 15910407) is a high-frequency electronic generator that steps up voltage via a ferritic-core transformer to deliver a secondary voltage of 15 kV and a secondary current of 20 mA. It operates on a 220–240 V supply at 50–60 Hz, consuming 45 W, with a duty cycle of 50%. The transformer features a single pole, a peak current of 45 mA, and an output voltage frequency of 6–10 kHz. It is designed for domestic, commercial, and industrial burner applications, offering a compact and lightweight construction with built-in varistor and overload protection. The unit complies with directives 2004/108/EC and 73/23/EEC, and has an IP00 protection rating.

When selecting an ignition transformer of this type, ensure the supply voltage, frequency, and secondary voltage/current ratings match the burner controller's requirements. Verify the mounting screw size (e.g., M4x45) and the type of high-voltage connection (threaded or Ø4 mm connector) to fit the existing assembly. The maximum ignition cable length and recommended spark distance must be compatible with the electrode setup. Power cable options include built-in cable or connector, with connector availability on request.

Typical failures of such ignition transformers include internal short circuits or open windings, often caused by overheating or voltage surges, leading to weak or no spark at the electrode. The equipment may fail to ignite, produce intermittent sparks, or trip the controller. Check for visible damage, measure secondary voltage with a suitable probe, and verify the varistor and overload protection functions.
