Brahma Ignition transformer TC1LVCS 15911200

The Brahma TC1LVCS ignition transformer (SKU 15911200) is a compact, high-frequency electronic device used in gas and liquid fuel burners for domestic, commercial, and industrial installations. It operates with a supply voltage of 220–240 V at 50–60 Hz, consuming 25 W, and generates a peak output voltage of 15 kV with a secondary current of 45 mA. The transformer features a 100% duty cycle, built-in short circuit protection, and an integrated varistor for surge protection. It has one contact, a recommended spark distance of 3–5 mm, and supports an ignition cable up to 1.5 m in length. 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 output voltage match the burner's requirements. The transformer must be compatible with the controller's connection system, typically using M4x45 screws for direct mounting. Verify the number of contacts and the high-voltage connection type (threaded or 4 mm connector) to match the existing setup. The standard power cable length is 560 mm, and the unit can be installed in any position, but the valve body must be connected to ground for safety.

Common failure modes for ignition transformers include internal short circuits, open circuits, or breakdown of the high-voltage insulation, often caused by moisture, overheating, or voltage surges. Symptoms may include no spark at the electrode, weak or intermittent sparking, or the burner failing to ignite. Check the transformer's output voltage with a suitable meter, inspect the high-voltage cable and connections for damage, and verify the supply voltage and grounding are correct.
