Brahma Ignition transformer TC1SVCA 15911051

The Brahma TC1SVCA ignition transformer, SKU 15911051, is a compact electronic device designed for burner ignition in gas and liquid fuel systems. It operates on a 220–240 V supply at 50–60 Hz, consuming 25 W, and generates a peak secondary voltage of 15 kV with a secondary current of 45 mA. The transformer features a 100% duty cycle, allowing continuous operation, and is rated for ambient temperatures from -10 to 60 °C. It has one high-voltage contact and supports an ignition cable up to 1.5 m in length, with a standard power cable of 560 mm. The recommended spark distance is 3–5 mm, and the output voltage frequency ranges from 6 to 10 kHz. The unit weighs 0.42 kg net.

When selecting a replacement ignition transformer of this type, verify that the supply voltage, frequency, and power consumption match the burner's electrical specifications. Ensure the secondary voltage and current are compatible with the ignition electrode and cable length. Check the number of high-voltage contacts (single or double) and the mounting configuration to fit the burner's design. Measure the physical dimensions and compare with the existing unit to confirm proper fitment. Also, confirm the duty cycle requirement (continuous or intermittent) and the operating temperature range for your application.

Common failure modes for ignition transformers include internal short circuits, open windings, or breakdown of insulation, leading to weak or no spark. Symptoms may include the burner failing to ignite, intermittent ignition, or a buzzing sound from the transformer. Check for visible damage, overheating, or carbon tracking on the high-voltage output. Verify the input voltage and continuity of the primary and secondary windings with a multimeter. Also, inspect the ignition cable and electrode for wear or improper gap, as these can cause excessive load and premature failure.
