Brahma Ignition transformer 15909025

Brahma Ignition transformer 15909025 is a single-output ignition transformer with a duty cycle of 100%, designed for use in atmospheric gas burners. It has a power consumption of 2.5 W, a recommended spark distance of 2–4 mm, and supports an ignition cable up to 1 m in length. The transformer weighs 0.055 kg, has protection class IP00, and can be installed in any position. It is compatible with BRAHMA TR2, Mora 5106.1032, and Thermona 5106.1032, and corresponds to type designations 01289096, ST15165, and 41651.

When selecting an ignition transformer of this type, ensure the output voltage, duty cycle, and number of outputs match the burner's requirements. The transformer must be compatible with the specific boiler model and its electrical circuit, including flame control and safety devices. Installation should be performed with power off, following national and European safety standards. The transformer can be mounted in any position, but high-voltage cables should be kept short and routed away from other cables to minimize interference. Grounding must be and arranged at a single point to prevent parasitic currents.

Typical failures of ignition transformers include internal short circuits or open windings, leading to no spark or weak spark at the electrode. This may cause the burner to fail to ignite or to ignite intermittently. Check the transformer's output voltage with a suitable meter, inspect the ignition cable for damage or excessive length, and verify the spark gap is within the recommended range. Also, ensure proper grounding and that the transformer is not overheating due to continuous operation beyond its duty cycle.
