Brahma Ignition transformer TB2SVCAF 15910560

The Brahma TB2SVCAF ignition transformer (SKU 15910560) is a high-frequency generator designed for ignition in gas and liquid fuel burners. It operates on a supply voltage of 220–240 V at 50–60 Hz, delivering a secondary voltage of 15 kV and a secondary current of 40 mA. The transformer has a duty cycle of 33%, power consumption of 46 W, and features two high-voltage outputs. It includes a built-in EMC filter and varistor, and is protected against dust and moisture to IP00. The device measures 106 mm in length, 74.5 mm in width, and 44.2 mm in height, with a net weight of 0.53 kg. It operates within an ambient temperature range of -10 to 60 °C and comes with a standard power cable length of 560 mm.

When selecting an ignition transformer of this type, ensure the supply voltage, frequency, and ignition voltage match the burner's requirements. The transformer must have the correct number of high-voltage outputs and compatible connectors for the ignition cables. Check the physical dimensions and mounting arrangement to fit the burner's housing. The duty cycle and power consumption should be suitable for the intended operation. Verify the ingress protection rating meets the installation environment's demands.

Common failures in ignition transformers include internal short circuits, open windings, or breakdown of insulation, leading to weak or no spark. Equipment may fail to ignite, causing burner lockout or repeated ignition attempts. Check for visible damage, overheating, or unusual noises. Measure the secondary voltage and current with appropriate test equipment to confirm output. Inspect the high-voltage cables and connections for wear or corrosion.
