Brahma Ignition transformer TC2SVCA 15911158

The Brahma TC2SVCA ignition transformer (SKU 15911158) is a compact, high-frequency electronic device designed for gas and liquid fuel burners. It operates on a 220–240 V, 50 Hz supply, consuming 55 W, and delivers a secondary voltage of 12 kV at 55 mA with a 10 kHz output frequency. The transformer features a ferritic core, built-in EMC filter, varistor protection, and short-circuit protection, with a duty cycle of 50%. It includes an ignition cable (max length 1.5 m) and a standard power cable of 560 mm, weighing 0.42 kg, with IP00 protection.

When selecting a replacement ignition transformer of this type, verify the supply voltage, frequency, and secondary voltage/current ratings match the burner controller's requirements. Check the mounting dimensions and connection system (e.g., threaded or 4 mm connector) to ensure compatibility with existing brackets and cables. The recommended spark distance of 3–5 mm and maximum ignition cable length (1.5 m) must be respected for proper operation. Ensure the duty cycle (50%) aligns with the burner's ignition cycling to avoid overheating.

Typical failures of this kind include internal short circuits or open windings, often caused by moisture ingress or voltage surges, leading to weak or no spark. The burner may fail to ignite, lockout, or produce intermittent ignition. Check for visible damage, measure secondary output with a suitable probe, and verify primary supply voltage and continuity of the ignition cable.
