Brahma Ignition transformer TD2LTCS 15911306

The Brahma TD2LTCS ignition transformer (SKU 15911306) is a high-frequency electronic generator with a ferritic core, designed for gas and liquid fuel burners in domestic, commercial, and industrial installations. It provides a secondary voltage of 12–12 kV at 55 mA, with an output frequency of 12 kHz. The transformer operates on a supply voltage of 110-120 V 50/60 Hz, consumes 30 W (30 VA), and has a 100% duty cycle. It features two poles, an integrated varistor for surge protection, and built-in short circuit protection. The unit weighs approximately 0.36 kg and has an IP00 protection class.

When selecting an ignition transformer of this type, ensure the supply voltage, frequency, and secondary voltage match the burner controller's requirements. Verify the number of high-voltage contacts (single or double) and the connection type (threaded or 4 mm connector). The transformer can be mounted in any position using M4x45 screws, and the valve body must be grounded. Check the recommended spark distance (3–5 mm) and the maximum ignition cable length (1.5 m) for proper installation.

Typical failures of such ignition transformers include internal short circuits or open circuits due to overheating or voltage surges, leading to weak or no spark at the electrodes. The burner may fail to ignite or intermittently lose flame. Check for visible damage, measure the secondary voltage with a suitable probe, and verify the primary supply and grounding. Also inspect the ignition cable and electrode gap for wear or incorrect spacing.
