Brahma Ignition transformer 15911050

The Brahma Ignition transformer 15911050 is an electronic ignition transformer with compact dimensions, designed for use in gas burners and light or heavy oil burners in domestic, commercial, and industrial installations. It operates on a high-frequency electronic generator principle, increasing voltage via a ferrite core transformer to achieve output values up to 15 kV. The ignition cable insulation is silicone, and the unit features a compact design. This transformer is energized only during the ignition phase under command from the burner control, stepping up mains voltage to generate a spark across the ignition electrode gap.

Parts of this type are selected primarily by secondary voltage and current, primary voltage (commonly 230 V, with 110 V and 24 V variants), duty cycle, mounting arrangement, terminal type, and cable connector pattern. When replacing, verify the original transformer's markings and compare mounting dimensions and pin arrangement against the unit to be installed. The physical footprint and connector pattern must match the existing installation, and the secondary output characteristic must match the electrode gap and burner control's timing.

Ignition transformers of this kind can fail due to cracked or hardened silicone-insulated cables, which may leak the spark to earth, causing a false indication of a faulty transformer. Other failure modes include internal component breakdown leading to no spark or weak spark, often resulting in ignition failure or intermittent operation. Before concluding the transformer is defective, inspect the cable and connector condition, and check for signs of overheating or physical damage.
