Brahma Ignition transformer 15910557

The Brahma Ignition transformer 15910557 is a compact high-frequency electronic device designed for gas and liquid fuel burners in domestic, commercial, and industrial installations. It operates on a supply voltage of 110-120 V 50/60 Hz and provides a secondary voltage of 12–12 kV with a secondary current of 30 mA. The transformer features a duty cycle of 50%, a peak current of 55 mA, and an output voltage frequency of 6–10 kHz. It includes built-in short circuit protection, a varistor, a ferritic core, and a high-frequency generator, with an IP00 protection rating. The unit weighs 0.36 kg and supports an ignition cable length up to 1.5 m, with a standard power cable length of 560 mm.

Ignition transformers of this type are selected based on supply voltage, secondary voltage, and connector configuration. Ensure the supply voltage matches the burner's electrical system, and verify the secondary voltage and current meet the ignition requirements. The transformer must be compatible with the burner's controller; for this series, compatibility with Brahma controllers is standard. Mounting options include direct installation with screws, and the high-voltage cable connection can be threaded or use a 4 mm connector. All connectors and cable options are available on request, so confirm the exact type needed before ordering.

Common failures in ignition transformers include short circuits, open circuits, or breakdown of insulation, leading to weak or no spark. Symptoms may include the burner failing to ignite, intermittent ignition, or a buzzing sound from the transformer. Check for visible damage, measure secondary voltage with a suitable probe, and inspect the ignition cable and spark gap for wear or incorrect spacing. Overheating or prolonged operation beyond the duty cycle can also cause failure.
