Brahma Ignition transformer TC2SVCA 15911152

The Brahma TC2SVCA ignition transformer (SKU 15911152) is an electronic, high-frequency step-up transformer with a ferritic core, designed for gas and liquid fuel burners. It operates on a 220–240 V supply at 50 Hz, consuming 55 W, and delivers a secondary voltage of 12–12 kV with a secondary current of 55 mA at a frequency of 10 kHz. The transformer features a 100% duty cycle, two high-voltage outputs, and built-in short-circuit protection and a varistor for voltage fluctuation resistance. It includes an integrated EMC filter to reduce electromagnetic interference, complies with directive 2004/108/EC, and has an IP00 protection rating. The unit weighs 0.42 kg, has a compact design, and is suitable for continuous operation with Brahma controllers.

When selecting a replacement ignition transformer of this type, ensure the supply voltage, frequency, and power consumption match the burner's electrical system. Verify the secondary voltage and current ratings, as well as the number of high-voltage outputs (single or double) and the type of high-voltage connection (threaded or Ø4 mm connector). The transformer must be compatible with the controller and mounting system; check the mounting dimensions and available connecting systems. Also confirm the maximum ignition cable length and recommended spark distance to ensure proper installation.

Common failures in ignition transformers of this kind include short circuits or open circuits in the secondary winding, leading to weak or no spark. Overheating due to prolonged operation or inadequate cooling can cause insulation breakdown, resulting in intermittent ignition or complete failure. Voltage surges may damage the internal varistor or electronic components, causing erratic operation. Symptoms on the equipment include failure to ignite, delayed ignition, or burner lockout. Check the transformer for visible damage, measure secondary voltage with a suitable probe, and verify the spark gap and cable integrity.
