Brahma Ignition transformer TD2LTCAF 15910462

The Brahma TD2LTCAF ignition transformer (SKU 15910462) is a compact, high-frequency electronic device designed for gas and liquid fuel burners. It operates on a 220–240 V supply at 50–60 Hz, consuming 55 W, and delivers a secondary voltage of 24 kV with a secondary current of 30 mA. The transformer features a ferritic core, polyester resin filling, and built-in varistor for surge protection, with a duty cycle of 50% and protection rating IP00. It has double-pin output, supports ignition cables up to 1.5 m, and includes a standard power cable of 560 mm. The unit weighs 0.36 kg and is available with optional continuous operation or connector versions on request.

When selecting an ignition transformer of this type, verify that the supply voltage, frequency, and power consumption match the burner's electrical system. Ensure the secondary voltage and current ratings are compatible with the ignition electrode gap (typically 3–5 mm) and cable length (max 1.5 m). Mounting options vary; this kind may use M4x45 screws for direct attachment to compatible controllers, and high-voltage connections can be threaded or via a 4 mm connector. Check the physical dimensions and mounting hole positions to fit the existing bracket, and confirm whether a built-in power cable or connector is required.

Typical failures in this kind of ignition transformer include internal short circuits due to moisture ingress or overheating, leading to no spark or weak spark at the electrodes. Overloads or voltage surges can damage the varistor or electronic components, causing intermittent ignition or complete failure. Symptoms on the burner include failure to ignite, delayed ignition, or burner lockout. Check for visible damage, measure secondary voltage with a suitable probe, and verify primary supply voltage and continuity of the ignition cable.
