Brahma Ignition transformer TC1LVCA 15911002

The Brahma TC1LVCA ignition transformer (SKU 15911002) is a high-frequency electronic device with a ferritic core, designed to generate ignition sparks for gas and liquid fuel burners. It operates on a supply voltage of 110-120 V at 50/60 Hz, producing a secondary voltage of 15 kV with a secondary current of 45 mA. The transformer features a 100% duty cycle, a single contact, and an integrated EMC filter, complying with directive 2004/108/ec. It has a net weight of 0.42 kg, a recommended spark distance of 3-5 mm, and a maximum ignition cable length of 1.5 m. The output voltage frequency ranges from 6 to 10 kHz, and the standard power cable length is 560 mm. The unit includes built-in short circuit protection and is rated IP00.

When selecting an ignition transformer of this type, ensure the supply voltage and frequency match the burner's electrical system. Verify the secondary voltage and current requirements of the ignition electrode, as well as the spark distance and cable length limits. The transformer must have the correct number of contacts and mounting configuration to fit the burner's connection system. Check the duty cycle to ensure it can handle the burner's operational cycle, and confirm that the EMC filter and compliance standards meet local regulations.

Common failures in ignition transformers include internal short circuits, open circuits in the secondary winding, or breakdown of insulation leading to arcing. Symptoms may include weak or no spark, intermittent ignition, or visible damage to the transformer casing. Check for continuity in the primary and secondary windings, inspect for signs of overheating or burn marks, and verify that the spark gap is within the recommended range. If the transformer fails, the burner may not ignite or may shut down due to flame detection failure.
