Brahma Ignition transformer 15897000

The Brahma Ignition Transformer 15897000 is a capacitive discharge ignition transformer designed for continuous operation in atmospheric gas burners. It operates on a supply voltage of 220–240 V at 50–60 Hz, delivering a secondary voltage of 20 kV with a discharge frequency of 25 Hz. The transformer has a power consumption of 2 W and a duty cycle of 100%. Its plastic housing is epoxy resin filled, providing insulation, and it features quick-release connections for both power (6.35x0.8) and high voltage (2.8x0.5). The unit measures 36 mm in length, 34 mm in width, and 54 mm in height, with a net weight of 0.08 kg.

When selecting an ignition transformer of this type, verify that the supply voltage, frequency, and secondary voltage match the burner's requirements. Check the physical dimensions and mounting style to ensure compatibility with the existing bracket or enclosure. The electrical connections must correspond to the quick-release terminals on the burner, and the maximum ignition cable length should not exceed the specified limit to avoid performance degradation. Installation must be performed with power off, and the valve body must be grounded at a single point to ensure safety.

Common failures in capacitive discharge ignition transformers include internal short circuits or open windings, often caused by moisture ingress or overheating. Symptoms may include no spark at the electrode, weak or intermittent sparking, or burner ignition failure. Check for visible damage to the housing, loose connections, and measure the secondary voltage with a suitable high-voltage probe to confirm output. Also inspect the ignition cable for cracks or excessive length, which can reduce spark energy.
