Fida Ignition transformer TZRDA

The Fida Ignition transformer TZRDA is a compact, single-spark transformer designed for gas and oil burners. It operates with a supply voltage of 230 V at 50 Hz and a primary current of 0.32 A. The secondary voltage determines the spark gap range, with a secondary current of 10 mA. It features a duty cycle of 100%, allowing continuous operation, and has an ingress protection rating of IP44. The transformer has one pole, measures 90 mm in length, 53 mm in width, and 69 mm in height, and includes an ignition cable connector with a plug of ø4 mm. Its article numbers are TZRDA and 462.820.033.

When selecting an ignition transformer of this type, ensure the primary voltage and frequency match the burner control output. The secondary voltage and current must be compatible with the electrode gap and spark energy requirements. Verify the physical dimensions, mounting points, and connector pattern (e.g., plug ø4 mm) align with the original part. Also, check the duty cycle rating to ensure it suits the burner's operational cycle.

Common failures include no spark, intermittent operation, or weak ignition. This can be caused by worn or damaged internal components, cracked or hardened high-tension cables that leak spark to earth, or incorrect primary voltage. Inspect the high-tension cables for damage and verify the transformer's primary voltage and connector integrity.
