Brahma Ignition transformer TC2LTCSF 15910658

The Brahma TC2LTCSF ignition transformer (SKU 15910658) is a high-frequency electronic transformer with a ferritic core, designed for gas and liquid fuel burners. It provides a peak output voltage of 2x12 kV, a peak current of 55 mA, and operates at a frequency of 8.5–12 kHz. The transformer has a supply voltage of 220–240 V (50/60 Hz) and a power consumption of 30 VA. It features a 100% duty cycle, built-in short circuit protection, and is available with an integrated EMC filter, complying with directive 2004/108/EC. The unit weighs 420 g, has an IP00 protection rating, and includes a standard power cable length of 560 mm.

When selecting an ignition transformer of this type, verify that the supply voltage, secondary voltage, and current ratings match the burner controller's requirements. The transformer can be mounted in any position, but ensure that high-voltage cables are not routed near other cables. The recommended spark distance is 3–5 mm, and the maximum ignition cable length is 1.5 m. Installation must comply with electrical safety standards such as EN60355-1 and EN50165, and the valve body must be grounded per EN60335-1.

Typical failures of this type of ignition transformer include internal short circuits or open windings, often caused by moisture ingress or overheating. Symptoms may include no spark at the electrode, intermittent ignition, or a buzzing sound from the transformer. Check the primary and secondary circuits for continuity, and inspect the high-voltage cable and spark electrode for damage or excessive gap.
