Brahma Ignition transformer TC1LVCAF 15910400

The Brahma TC1LVCAF ignition transformer (SKU 15910400) is an electronic device with a ferritic core, designed for gas and liquid fuel burners in domestic, commercial, and industrial installations. It operates on a supply voltage of 220–240 V at 50–60 Hz, producing a maximum output voltage of 15 kV with a rated secondary current of 20 mA and a peak current of 45 mA. The output voltage frequency ranges from 6 to 10 kHz, and the recommended spark distance is 3–5 mm. It features a built-in filter to reduce electromagnetic interference, short-circuit and overload protection, and complies with directives 73/23/EEC and 2004/108/EC. The transformer has a single pole, weighs 0.42 kg, and supports an ignition cable up to 1.5 m in length, with a standard power cable of 560 mm.

When selecting an ignition transformer of this type, verify that the supply voltage, frequency, and output voltage match the burner's requirements. Check the mounting and connecting systems, as these transformers offer various options, including single or double-pin high-voltage output and built-in power cable or connector. Ensure the high-voltage cable length does not exceed the maximum specified for the model, and confirm the spark distance is set correctly. The transformer can be used with compatible Brahma controllers, which may be mounted directly using M4x45 screws.

Typical failures of this kind of ignition transformer include loss of spark or weak spark, often caused by internal short circuits or overloads. The equipment may fail to ignite or exhibit intermittent ignition. Check for visible damage, ensure the spark gap is within the recommended range, and verify that the supply voltage is stable. If the transformer has a built-in filter, electromagnetic interference issues may indicate a fault.
