Brahma Ignition transformer TC1LVCA 15911000

The Brahma TC1LVCA ignition transformer (SKU 15911000) is a high-frequency electronic generator with a ferritic core, designed for gas and liquid fuel burners. It operates on a supply voltage of 220–240 V at 50–60 Hz, consuming 25 W. The transformer delivers a secondary voltage of 15 kV with a secondary current of 45 mA, and an output voltage frequency of 6–10 kHz. It features a single pole, built-in short circuit protection, and a varistor for surge protection. The unit weighs 0.42 kg and has an ingress protection rating of IP00.

When selecting an ignition transformer of this type, ensure the supply voltage, frequency, and power consumption match the burner's electrical specifications. Verify the secondary voltage and current requirements of the ignition electrode, as well as the maximum ignition cable length (1.5 m) and standard power cable length (560 mm). The recommended spark distance is 3–5 mm. Mounting and connecting systems vary, so confirm the physical dimensions and contact configuration (number of poles) fit the burner's design. The duty cycle (50%) must be compatible with the burner's operational cycle.

Typical failures of ignition transformers include internal short circuits, open circuits, or breakdown of insulation, often due to moisture or overheating. Symptoms on the equipment include weak or no spark at the electrode, intermittent ignition, or burner lockout. Check the secondary voltage and current output with appropriate test equipment, inspect the ignition cable for damage, and verify the spark gap is within the recommended range. Also, ensure the supply voltage is stable and within specifications, as surges can damage the internal varistor.
