Brahma Ignition transformer TD1STCAF 15910526

This high-frequency electronic ignition transformer is designed for gas and liquid fuel burners in home, commercial, and industrial installations. It operates from a 220–240 V supply at 50–60 Hz and generates a 15 kV ignition voltage with a rated current of 25 mA. The unit has a single contact, consumes 45 W, and is rated for a 50% duty cycle. It includes a built-in EMC filter, a varistor, and built-in short circuit protection. The transformer weighs 0.36 kg, has IP00 protection, and supports an ignition cable up to 1.5 m. Recommended spark distance is 3–5 mm.

When choosing a replacement ignition transformer of this type, check the supply voltage, secondary voltage, and rated current against the original unit. These transformers are designed for direct mounting on Brahma controllers using M4x45 screws. The high-voltage output is available as single or double pin, and the cable connection can be threaded or with a Ø4 mm connector, so verify the existing configuration before ordering. Confirm the required duty cycle to ensure the replacement matches the application.

Failed ignition transformers typically prevent spark generation, resulting in the burner failing to ignite or intermittent ignition attempts. The equipment may display a lockout or fault code. Check for visible damage to the transformer casing or insulation, measure output voltage under no-load conditions (should approach 15 kV), and verify continuity in the ignition cable up to the spark electrode.
