Brahma Ignition transformer 15910508

The Brahma Ignition transformer 15910508 is a high-frequency electronic generator designed for ignition in gas and liquid fuel burners. It operates at a supply voltage of 110–120 V and 50 Hz, delivering a secondary voltage of 15 kV with a rated current of 25 mA and a peak current of 45 mA. The transformer features a ferritic core, built-in varistor and short-circuit protection, and is protected to IP00. It has a duty cycle of 50%, an operating temperature range of -10 to 60 °C, and weighs approximately 0.36 kg. The device is compact and lightweight, with various mounting and connecting systems, and includes an EMC filter, eliminating the need for external filters.

When selecting an ignition transformer of this type, ensure the supply voltage, frequency, and output voltage match the burner's requirements. Check the number of contacts and the mounting screw size (e.g., M4x45) for compatibility with the controller. The transformer may come with a built-in power cable or a connector, and high-voltage cable connections can be threaded or via a 4 mm connector. Verify the recommended spark distance and maximum ignition cable length for proper installation.

Typical failures of ignition transformers include short circuits or open circuits in the high-voltage output, often caused by insulation breakdown or moisture ingress. Symptoms may include weak or no spark, intermittent ignition, or burner lockout. Check the spark gap, ignition cable condition, and the transformer's output voltage with a suitable tester. Overheating or prolonged operation can lead to internal component failure, so inspect for signs of burning or discoloration.
