Fida Ignition transformer TF082C02

The Fida Ignition Transformer TF082C02 is a component designed for the ignition phase of burner systems, specifically fitting the Fida Compact 8/20CM. It operates with a duty cycle of 20%, indicating the maximum on-time relative to a full cycle. The transformer features silicone-insulated ignition cables to withstand high voltage and heat. Its function is to step up the mains voltage to a level sufficient for a spark across the electrode gap, ensuring ignition of the fuel mixture.

When selecting a replacement ignition transformer of this type, verify the primary voltage (commonly 230 V, but also 110 V or 24 V), the secondary output (voltage and current), and the mechanical fit, including the high-voltage connector pattern. The duty cycle rating, such as 20%, must match the burner's cycling frequency. Ensure the mounting and terminal types are compatible with the existing setup.

Failure of ignition transformers of this kind often results in no spark at the electrode, leading to ignition failure or intermittent starting. A hardened or cracked ignition cable can leak the spark to earth, which may imitate a faulty transformer. Check the condition of the silicone-insulated cables and verify the transformer's output with a multimeter during the ignition phase.
