Brahma Ignition transformer TD2LTCSF 15910666

The Brahma TD2LTCSF ignition transformer (SKU 15910666) is a high-frequency electronic device designed for gas and liquid fuel burners. It operates on a 220–240 V supply at 50–60 Hz, consuming 30 W, and delivers a secondary voltage of 12–12 kV with a current of 55 mA. The transformer features a ferritic core, built-in short-circuit and varistor protection, and an EMC filter, complying with directive 2004/108/EC. It has a 100% duty cycle, IP00 protection, and a compact, lightweight design (approx. 360 g). The unit provides two high-voltage outputs, configurable as single or double-pin, with a recommended spark distance of 3–5 mm and a maximum ignition cable length of 1.5 m.

When selecting a replacement ignition transformer of this type, ensure the supply voltage, frequency, and power consumption match the burner's electrical system. Verify the secondary voltage and current requirements of the ignition electrode, as well as the duty cycle (continuous operation is indicated by 100%). Check the mounting and connection systems: high-voltage connections may be threaded or connector type, and power cable options include built-in cable or connector. Measure the physical dimensions and weight to confirm compatibility with the burner housing, and ensure the spark distance and cable length are within the specified limits. For Brahma controllers, direct mounting may be possible using M4x45 screws.

Common failures in high-frequency electronic ignition transformers include internal short circuits due to moisture or overheating, leading to no spark or weak spark at the electrode. Overvoltage surges can damage the varistor, causing the transformer to stop functioning. Physical damage to the high-voltage cable or connector can result in arcing or intermittent ignition. If the burner fails to ignite or exhibits erratic sparking, check the transformer's output voltage and current, inspect for visible damage or burn marks, and verify the integrity of all connections and the spark gap.
