Brahma Ignition transformer TC2STCAF 15910551

The Brahma Ignition transformer TC2STCAF 15910551 is a compact device designed for gas and liquid fuel burners. It operates on a 220–240 V supply at 50 Hz, with a secondary voltage of 24 kV and a secondary current of 55 mA. The transformer features a high-frequency electronic generator and a ferritic core, delivering an output voltage up to 15 kV. It has a duty cycle of 50%, a rated current of 27 mA, and an output voltage frequency of 6 kHz. The unit includes an integrated EMC filter, built-in short circuit protection, and a varistor for surge protection. It weighs 0.42 kg and is certified to IMQ resolution and low voltage directive 73/23/EEC.

Ignition transformers of this type are selected by matching the supply voltage, secondary voltage, and current ratings to the burner's requirements. The mounting system must align with the burner's design, often using M4x45 screws for direct controller attachment. The ignition cable length should not exceed the specified maximum, and the spark distance must be set within the recommended range. Compatibility with the burner's controller is essential, and various connection options (threaded or connector) are available to suit different installations.

When ignition transformers fail, common symptoms include no spark or weak spark at the electrode, leading to ignition failure or intermittent burner operation. The transformer may overheat or produce a buzzing sound due to internal short circuits or component degradation. Check the secondary voltage output, spark gap, and cable integrity. Also inspect for signs of arcing or damage to the high-voltage output and ensure the supply voltage is within specifications.
