Brahma Ignition transformer TR2/A 15909104

The Brahma Ignition transformer TR2/A 15909104 is a single-pole ignition transformer with a secondary voltage of 15 kV and a 100% duty cycle. It is equipped with an electromagnetic filter to reduce electromagnetic interference. The transformer has an ingress protection rating of IP00, a net weight of 0.055 kg, and a length of 45 mm. It is designed for use in atmospheric gas burners and can be installed in any position. The recommended spark distance is 2–4 mm, and the maximum ignition cable length is 1 m.

When selecting an ignition transformer of this type, ensure that the secondary voltage, duty cycle, and number of poles match the burner's requirements. The transformer's dimensions and mounting configuration must be compatible with the existing installation. Check the recommended spark distance and maximum ignition cable length to ensure proper operation. The transformer can be installed in any position, but the high-voltage cable should be kept as short as possible and routed away from other wiring to minimize interference.

Common failure modes for ignition transformers include internal short circuits, open windings, or breakdown of insulation, leading to weak or no spark. Symptoms may include the burner failing to ignite, intermittent ignition, or the transformer overheating. Check for visible damage, measure the secondary voltage with a suitable probe, and inspect the spark electrode and cable for wear or damage.
