Description
The Cofi Ignition transformer TRK1-30CHD is a step-up transformer used to generate a high-voltage spark for automatic ignition systems in gas and liquid fuel burners. It operates on a supply voltage of 220–240 V at 50–60 Hz. The transformer measures 85 mm in length, 70 mm in width, and 40 mm in height, with a net weight of 0.34 kg. It is supplied with silicone-insulated ignition cables. The product is identified by SKU TRK1-30CHD and article number 309.820.041.
Further details
| Advantages | compact housing, stable spark formation, reliable burner ignition, suitable for gas and liquid fuel burners, original Cofi product, long service life |
|---|---|
| Application scope | gas burners, liquid fuel burners, combination burners, boiler equipment, heat generators, automatic ignition systems |
| Operating phase | active only during the ignition phase |
| Replacement considerations | verify primary voltage and secondary output match burner control and electrode gap requirements; inspect ignition cables |
Choosing and fitting
When selecting a replacement ignition transformer of this type, verify that the primary voltage matches the burner control (commonly 230 V, but 110 V and 24 V versions exist) and that the secondary output is suitable for the electrode gap. Check the mounting style and terminal type, as well as the cable connector pattern. Ensure the ignition cables are silicone-insulated to withstand high voltage and heat. Measure the physical dimensions to confirm fit within the burner housing.
Signs of failure
Typical failures of ignition transformers include internal short circuits or open windings, leading to no spark or weak spark. The burner may fail to ignite or cycle on safety lockout. Check the ignition cables for hardening or cracking, which can cause spark leakage to earth and mimic a defective transformer. Inspect the transformer for signs of overheating or burn marks.
