Fida Ignition transformer TE105D01

The Fida Ignition transformer TE105D01 is a dual-spark, compact transformer designed for intermittent operation in industrial burners. It operates on a supply voltage of 230 V at 50–60 Hz, delivering a secondary current of 30 mA with a duty cycle of 15%. The transformer provides a secondary voltage of 0.002 kV (2 V) and can reach a peak voltage of up to 14 kV. It features a sealed plastic housing with IP44 ingress protection, plug-in ø4 mm ignition cable connectors, and silicone-insulated cables. The unit measures 115 mm in length, 86 mm in width, and 70 mm in height, with a net weight of 1.9 kg. It is manufactured in Italy.

When selecting a replacement ignition transformer of this kind, ensure the supply voltage, frequency, secondary voltage, current, and duty cycle match the burner's requirements. The mounting style and dimensions must fit the existing bracket, and the ignition cable connector type (e.g., plug-in ø4 mm) should be compatible. Measure the physical dimensions and compare the electrical specifications before ordering. Also, verify the ingress protection rating suits the installation environment.

Typical failures of ignition transformers include no spark, weak spark, or intermittent operation. This can be caused by internal component failure, cracked or hardened ignition cables that leak voltage to ground, or damaged connectors. Before condemning the transformer, inspect the ignition cable for insulation damage and ensure all connections are secure. If the cable is faulty, replacing it may resolve the issue without replacing the transformer.
