Brahma Ignition transformer TD1LTCSF 15910631

The Brahma TD1LTCSF ignition transformer (SKU 15910631) is a component designed to generate a high-voltage pulse for igniting gas and liquid fuel burners. It operates on a supply voltage of 22–24 V and is used in automatic ignition systems for boiler and industrial equipment. The transformer features silicone-insulated ignition cable and insulated secondary winding. It is energized at the start of the firing sequence and de-energized once flame is proved.

When selecting a replacement ignition transformer of this type, verify the primary supply voltage (common values include 230 V, 110 V, and 24 V), secondary voltage and current, duty cycle, mounting dimensions, terminal configuration, and cable connector pattern. Confirm that the high-voltage cable is silicone-insulated and in good condition, as a hardened or cracked cable can leak spark to earth. Ensure the duty cycle matches the burner's ignition schedule, and check mounting dimensions and terminal orientation against the existing installation.

Typical failures of ignition transformers include no spark generation, weak spark, or intermittent sparking, which can result in ignition failure or burner shutdown. Check the high-voltage cable for damage, as a hardened or cracked cable can leak spark to earth, mimicking a faulty transformer. Also verify the supply voltage and connections, as incorrect voltage or loose terminals can cause similar symptoms.
