Brahma Ignition transformer TCD1FAV 15930023

The Brahma Ignition transformer TCD1FAV (SKU 15930023) is a high-frequency electronic generator with a ferritic core, designed for gas and liquid fuel burners. It operates at a supply voltage of 230 V and 50 Hz, producing a secondary voltage of 6 kV with a secondary current of 37 mA. The transformer features a built-in short circuit protection, varistor protection, and an integrated filter, complying with directives 2004/108/EC and 2006/95/EC. It has a duty cycle of 33%, a peak current of 83 mA, and an output voltage frequency of 13 kHz. The device is compact, weighs 0.25 kg, and is compatible with Brahma TC and TD series, with a maximum ignition cable length of 1.5 m and a recommended spark distance of 3–5 mm.

When selecting an ignition transformer of this type, ensure the supply voltage, frequency, and secondary voltage match the burner's requirements. The mounting and connecting systems vary, so verify the physical dimensions and connector type (e.g., single or double-pin) against the existing unit. The transformer's dimensions are compatible with TC and TD series, but always compare the mounting holes and high-voltage output configuration. The ignition cable length and spark distance must be within the specified limits for proper operation.

Typical failures of ignition transformers include short circuits, open circuits, or breakdown of the high-voltage insulation, often caused by moisture, overheating, or voltage surges. Symptoms on the equipment include no spark at the electrode, weak or intermittent sparking, or burner ignition failure. Check the primary and secondary circuits for continuity, inspect the high-voltage cable and connections for damage, and verify the spark gap is within the recommended range. If the transformer overheats or trips, inspect the duty cycle and ensure the cooling is adequate.
