Fida Ignition transformer TF082D

The Fida Ignition transformer TF082D is a component used in burner ignition systems to convert the 230 V supply voltage into a high-voltage output of 8 kV at a frequency of 50 Hz. It operates with a duty cycle of 20%, meaning it is designed for intermittent use during the ignition phase only. The transformer features a compact and robust housing, a triangular plug connector for electrical connection, and a 4 mm ignition cable connector. It is compatible with Fida Compact 8/20 M burners and is identified by manufacturer codes TF082D and 462.820.030.

When selecting a replacement ignition transformer of this type, ensure the primary voltage, secondary voltage, frequency, and duty cycle match the original specifications. The mounting arrangement, terminal type, and connector pattern must fit the burner panel. Measure the physical dimensions and compare the terminal layout before ordering. The high-voltage cable must be silicone-insulated to withstand heat and voltage.

Common failures of ignition transformers include internal short circuits, open windings, or insulation breakdown, leading to weak or no spark at the electrode. Symptoms may include the burner failing to ignite, intermittent ignition, or a no-flame condition. Check the ignition cable for cracks or damage, as a deteriorated cable can leak the spark to earth, mimicking a faulty transformer.
