Cofi Ignition transformer TRG1230/4

The Cofi TRG1230/4 is an ignition transformer designed for low-power diesel and fuel oil burners. It operates on a 230 V, 50 Hz supply and generates a high-voltage spark for ignition. This model is manufactured in Italy and features silicone-insulated ignition cables. Its compact design facilitates installation in various burner types, and its robust housing protects against vibration and temperature loads.

When selecting a replacement ignition transformer of this type, verify that the primary voltage (e.g., 230 V), secondary output, and physical mounting match the existing installation. Check the terminal type and cable connector pattern. Always confirm compatibility with the burner or boiler documentation before ordering.

Ignition transformers of this kind can fail due to cracked or hardened ignition cables, which may leak the spark to earth and mimic a faulty transformer. Other failure modes include internal short circuits or open windings, leading to weak or no spark. Check the cable condition first, then test the transformer's output.
