Brahma Ignition transformer TD2STPAF 15910556

The Brahma TD2STPAF ignition transformer (SKU 15910556) is a high-frequency electronic generator designed for gas and liquid fuel burners. It operates on a 220–240 V supply at 50–60 Hz, consuming 55 W, and features a ferritic core transformer that boosts voltage to 15 kV. With a duty cycle of 50%, it provides two high-voltage outputs with a peak current of 55 mA and a rated current of 30 mA. The unit includes a built-in varistor for voltage fluctuation resistance, short-circuit protection, and an integrated EMC filter, eliminating the need for an external filter. It is compact, lightweight (0.36 kg net), and suitable for domestic, commercial, and industrial applications.

When selecting an ignition transformer of this type, ensure the supply voltage, frequency, and duty cycle match the burner's requirements. Verify the number of high-voltage outputs and the spark distance (typically 3–5 mm) align with the electrode configuration. The transformer must be compatible with the controller model, and mounting options (e.g., direct installation with M4x45 screws) should be checked. Also confirm the power cable length and high-voltage connection type (threaded or Ø4 mm connector) suit the installation.

Typical failures of such transformers include loss of ignition spark, intermittent sparking, or no output due to internal component degradation. The burner may fail to ignite or shut down during operation. Check for visible damage, measure output voltage with a suitable probe, and verify the supply voltage and connections. Overheating or short circuits can cause the built-in protection to activate, leading to a complete loss of function.
