Brahma Ignition transformer TCD1FA 15930020

The Brahma Ignition Transformer TCD1FA (SKU 15930020) is a compact, high-frequency electronic ignition transformer designed for gas and liquid fuel burners. It operates with a supply voltage of 230 V at 50 Hz, delivering a secondary voltage of 6 kV and a secondary current of 37 mA. The transformer features a built-in filter, short-circuit protection, and varistor protection, and complies with directives 2004/108/EC and 2006/95/EC. It has a duty cycle of 33%, a recommended spark distance of 3–5 mm, and a maximum ignition cable length of 1.5 m. The unit weighs approximately 0.25 kg and is compatible with TC and TD series dimensions.

When selecting an ignition transformer of this type, ensure the supply voltage, frequency, and output voltage match the burner's requirements. Check the mounting and connecting systems, as various configurations are available, including single or double-pin high-voltage outputs. The transformer's dimensions should be compatible with the existing mounting space, and the ignition cable length must not exceed the specified maximum. Verify the protection rating and installation position suitability for the environment.

Common failure modes for ignition transformers include internal short circuits, open circuits, or insulation breakdown, often caused by overheating, moisture ingress, or voltage surges. Symptoms may include weak or no spark, intermittent ignition, or burner lockout. Check for visible damage, measure the output voltage with a suitable probe, and inspect the ignition cable and spark gap for wear or corrosion.
