Brahma Ignition transformer 15898000

Brahma Ignition transformer 15898000 is a compact ignition transformer designed for gas pre-mixing burners in condensing boilers. It operates with a supply voltage of 220–240 V and a frequency of 50–60 Hz, delivering a spark frequency of 200 Hz. The transformer includes a built-in filter and has a duty cycle of 50%. It is compatible with Brahma controllers CM32PR, MT11/MT31, MT191/MT391, and DM...PR, and fits Pictor condensing 55-85 boilers. The unit weighs 0.14 kg and measures 4.2x8.3x3.3 cm, with an ingress protection rating of IP00.

When selecting an ignition transformer of this type, ensure the supply voltage, frequency, and spark frequency match the burner's requirements. Verify the physical dimensions and mounting configuration to fit the available space. The transformer must be compatible with the controller model and the boiler's grounding system. Installation should follow safety standards, with the valve body connected to ground and grounding arranged at a single point. The transformer can be installed in any position, but high-voltage cables should be kept short and routed away from other cables.

Typical failures of ignition transformers include loss of spark, intermittent ignition, or no ignition at all. This may be due to internal component failure, short circuits, or damage from moisture or contamination. Check the power supply, connections, and the condition of the ignition cable. If the transformer overheats or produces a weak spark, it may need replacement. Ensure the duty cycle is respected to prevent overheating.
