Brahma Ignition transformer TC1STPAF 15910504

The Brahma TC1STPAF 15910504 is a high-frequency electronic ignition transformer designed for gas and liquid fuel burners. It operates on a 220–240 V supply at 50 Hz, consuming 45 W, and delivers a secondary voltage of 15 kV with a rated current of 20 mA and a peak current of 45 mA. The transformer features a ferritic core, integrated EMC filter, and built-in short circuit protection, with an IP00 protection class. It has a duty cycle of 50%, a recommended spark distance of 3–5 mm, and supports an ignition cable up to 1.5 m in length. The unit is compact and lightweight, weighing 0.42 kg, and includes a standard power cable of 560 mm.

When selecting an 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 are compatible with the ignition electrode and cable length. The transformer must have the correct number of high-voltage outputs (single or two-pin) and mounting arrangement to fit the burner. Check the protection class and duty cycle to ensure suitability for the operating environment and ignition cycle.

Common failure modes for ignition transformers include internal short circuits, open windings, or breakdown of insulation, leading to weak or no spark. Symptoms may include the burner failing to ignite, intermittent ignition, or visible arcing or burning at the high-voltage output. Check for proper supply voltage, continuity of the ignition cable, and signs of overheating or damage to the transformer housing.
