Brahma Ignition transformer 15909105

The Brahma Ignition Transformer 15909105 is a single-output ignition transformer designed for gas devices, reducing electromagnetic interference. It operates at a secondary voltage of 15 kV with a frequency of 15 kHz and consumes 2.5 W of power. The transformer has a duty cycle of 100%, allowing continuous operation, and is rated for an operating temperature range of -20 to 60 °C. It features an ingress protection rating of IP00 and weighs 0.055 kg. 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 output voltage, frequency, and power consumption match the burner's requirements. The transformer must be installed in any position, but grounding at a single point is essential to prevent parasitic currents. The ignition cable should be kept as short as possible and routed close to the ground busbar to minimize interference. Installation should be performed only with the power off, following national and European safety standards.

Ignition transformers of this kind may fail due to insulation breakdown, leading to weak or no spark. Symptoms include intermittent ignition, burner lockout, or failure to start. Check for visible damage, carbon tracking, or short circuits in the high-voltage cable and connections. Ensure the spark gap is within the recommended range and that the transformer is properly grounded.
