Brahma Ignition transformer TC1SVCAF 15910500

The Brahma TC1SVCAF ignition transformer, SKU 15910500, is a compact device used in gas and liquid fuel burners for domestic, commercial, and industrial applications. It operates on a supply voltage of 110-120 V at 50/60 Hz and generates a secondary voltage of 15 kV with a rated current of 20 mA. The transformer features a ferritic core, built-in short circuit protection, and complies with directive 2004/108/EC without requiring an external filter. It has a duty cycle of 50%, a peak current of 45 mA, and a recommended spark distance of 3-5 mm. The unit weighs approximately 0.42 kg and includes a standard power cable length of 560 mm, with a maximum ignition cable length of 1.5 m.

When selecting an ignition transformer of this type, ensure the supply voltage and frequency match the burner's electrical system. The mounting configuration, including the number of poles and screw type (e.g., M4x45), must align with the controller and burner design. Verify the high-voltage output connection type (threaded or Ø4 mm connector) and the required ignition cable length. Compatibility with the burner's controller is essential, as the transformer is designed to be used with specific controllers.

Common failures in ignition transformers of this kind include short circuits or open circuits in the high-voltage output, leading to weak or absent sparks. Overheating or insulation breakdown may cause intermittent ignition or complete failure. Check for visible damage, measure the secondary voltage with a suitable probe, and inspect the spark electrodes for proper gap and condition.
