Brahma Ignition transformer TC1LTCSF 15910659

The Brahma Ignition Transformer TC1LTCSF (SKU 15910659) is a component designed to step up the mains voltage to produce a spark across the ignition electrode gap in gas burners. It operates only during the ignition period, under command from the burner control, and is de-energized once the flame is proved. The transformer features silicone-insulated ignition cables to withstand high voltage and heat. This model is intended for precise control of gas burner valves, providing opening and closing when voltage is applied.

When selecting an ignition transformer of this type, verify the primary voltage (typically 230 V, but 110 V and 24 V variants exist) and the secondary voltage and current to match the electrode gap and burner requirements. Check the duty cycle to avoid overheating, and ensure the mounting type, terminal configuration, and cable connector pattern are compatible with the existing burner assembly. The ignition cable insulation must be intact; a hardened or cracked cable can leak spark to earth.

Typical failures include overheating due to prolonged energization, which can damage the transformer. A hardened or cracked ignition cable can leak the spark to earth, presenting symptoms similar to a faulty transformer, such as no spark or weak spark. Check the cable insulation and the transformer's operation during the ignition sequence.
