Brahma Ignition transformer TCD1BA 15930000

The Brahma TCD1BA ignition transformer (SKU 15930000) is a compact, high-frequency electronic generator designed for gas and liquid fuel burners in domestic, commercial, and industrial installations. It operates at a supply voltage of 230 V and 50 Hz, producing a secondary voltage of 6 kV with a peak output of 17 kV. The transformer delivers a rated current of 37 mA and a peak current of 83 mA, with an output frequency of 13 kHz. It features a ferritic core, built-in EMC filter, short-circuit protection, and varistor protection, and complies with directives 2004/108/EC and 2006/95/EC. The unit has a duty cycle of 33%, weighs approximately 0.25 kg, and is rated IP00.

When selecting an ignition transformer of this type, ensure the supply voltage, frequency, and output voltage match the burner controller's requirements. The transformer must have the correct mounting configuration and connector type (e.g., triangular SP1 or 6.35x0.8) to fit the existing wiring. Verify the high-voltage output connection (Ø4 mm connector or threaded) and the maximum ignition cable length (1.5 m) to ensure compatibility. Installation can be in any position, but high-voltage cables must be kept away from other cables, and the valve body must be grounded for safety.

Typical failures of ignition transformers include internal short circuits or open windings, often caused by overheating or voltage surges. Symptoms may include no spark at the electrode, weak or intermittent ignition, or burner lockout. Check for visible damage, measure the secondary voltage with a suitable probe, and verify the primary supply voltage and ground connection. A built-in varistor protects against surges, but repeated overvoltage can still damage the unit.
