Brahma Ignition transformer TC2LTCSF 15910656

The Brahma TC2LTCSF ignition transformer (SKU 15910656) is a compact electronic transformer for gas and liquid fuel burners. It provides a secondary voltage of 24 kV and a secondary current of 55 mA, with a duty cycle of 100%. The transformer operates at a supply voltage of 110–120 V and a frequency of 50–60 Hz, producing an output voltage frequency of 8.5–12 kHz. It features a built-in short circuit protection and is available with an integrated EMC filter, complying with directive 2004/108/EC. The unit has 2 poles, weighs 0.42 kg, and supports an ignition cable up to 1.5 m, with a standard power cable length of 560 mm. The recommended spark distance is 3–5 mm, and the ingress protection rating is IP00.

When selecting an ignition transformer of this type, ensure the supply voltage, frequency, and secondary voltage/current ratings match the burner controller's requirements. Verify the number of high-voltage output poles (single or double) and the mounting and connecting systems available. Measure the required ignition cable length and ensure it does not exceed the maximum specified for the transformer. Also, check the duty cycle (e.g., 100% or intermittent) to match the application's operational demands.

Typical failures of ignition transformers include internal short circuits, open windings, or breakdown of insulation, often due to moisture or overvoltage. Symptoms on the equipment include no spark at the electrode, weak or intermittent spark, or burner ignition failure. Check the transformer's input voltage, output spark, and the condition of the ignition cable and electrode gap. Also, inspect for physical damage or overheating signs.
