Brahma Ignition transformer TD1LTCSF 15910675

The Brahma TD1LTCSF ignition transformer (SKU 15910675) is a compact, high-frequency electronic device designed for ignition in burners. It operates with a supply voltage of 220–240 V at 50–60 Hz, delivering a secondary voltage of 15 kV and a secondary current of 45 mA. The transformer has a 100% duty cycle, consumes 25 W, and features a ferritic core, built-in short circuit protection, and an integrated EMC filter. It weighs 0.36 kg and is rated IP00, with a maximum ignition cable length of 1.5 m and a standard power cable length of 560 mm. The unit complies with the Low Voltage Directive (LVD) 73/23/EEC and holds an IMQ permit.

When selecting an ignition transformer of this type, ensure the supply voltage, frequency, and secondary voltage/current ratings match the burner's requirements. Verify the number of contacts (e.g., 1) and the connection type (e.g., plug connectors) to fit the existing wiring. The transformer can be mounted in any position, but the mounting screw size (e.g., M4x45) must be compatible with the controller or bracket. Check the maximum ignition cable length and the standard power cable length to ensure they meet the installation's needs.

Typical failures of ignition transformers include short circuits or open circuits in the secondary winding, leading to weak or no spark. Overheating due to prolonged operation or voltage surges can cause internal component damage, resulting in intermittent ignition or complete failure. Check for visible damage, measure the secondary voltage with a suitable probe, and verify the primary supply voltage and connections. If the transformer is suspected, test it with a known good unit or replace it with a compatible model.
