Brahma Ignition transformer T11/M 15093001

The Brahma ignition transformer T11/M 15093001 is designed for use in burners operating on liquid or gaseous fuels. It operates with a supply voltage of 220 V at 50 Hz, providing a secondary voltage of 9 kV and a secondary current of 20 mA. The transformer has a duty cycle of 33% in 3 minutes and consumes 240 W of power. Its body is made of PBT with 30% fiberglass, and it weighs 2 kg. The unit measures 110 mm in length, 96 mm in width, and 78 mm in height, with insulation made of polyester resin.

When selecting an ignition transformer of this type, ensure that the supply voltage, frequency, secondary voltage, and current ratings match the burner's requirements. The mounting system may vary; models with standard mounting are designated without a suffix letter, while others may include a letter indicating a different mounting arrangement. Check the physical dimensions and connection type (e.g., screw terminal) to ensure compatibility with the existing setup. The transformer can be installed in any position, but proper grounding is essential for safe operation.

Common failure modes for ignition transformers include insulation breakdown, which can cause short circuits or loss of spark. Symptoms may include the burner failing to ignite or intermittent ignition. Check for visible damage to the casing or connections, and verify the output voltage with a suitable meter. Ensure the ground connection is secure, as poor grounding can lead to erratic behavior.
