Fida Compact ignition transformer 10/20CM TE101D

The Fida Compact ignition transformer 10/20CM TE101D is an electronic step-up transformer used in fuel burners. It is supplied at 230 V, 50 Hz and provides a secondary voltage of 10 kV. The compact housing protects the internal components, and plugs are used for electrical connection. An LED indicator is present to show operational status. It operates only during the ignition phase under burner control to generate the spark for the fuel-air mixture.

Parts of this type are selected primarily by their electrical specifications: secondary voltage and current, primary voltage (230 V is the most common, though 110 V and 24 V versions exist), and duty cycle. The physical mounting arrangement, terminal type, and cable connector pattern must match the existing installation. When replacing an ignition transformer, ensure that the primary voltage matches the burner circuit and that the secondary output is compatible with the electrode gap and the control box safety time. The duty cycle must be adequate for the burner's ignition period. Check the condition of the high-voltage cable and connectors; if they show signs of tracking or brittleness, replace them as well.

Ignition transformers of this kind can fail when the high-voltage cable insulation hardens or cracks. This allows the spark to leak to earth, causing ignition failure that may be mistaken for a defective transformer. Inspect the cable and connectors for signs of tracking or brittleness, and replace them if necessary.
