Cofi Ignition transformer TRS818PC/1

The Cofi Ignition transformer TRS818PC/1 is a high-voltage ignition transformer designed for use in low-power diesel and heavy oil burners. It operates on a supply voltage of 110 V at a frequency of 50 Hz. This transformer generates a stable spark to ensure ignition of the fuel. It is manufactured in Italy and is intended for installation in heating boilers, heat generators, and industrial equipment.

When selecting an ignition transformer of this type, verify that the primary voltage and frequency match the burner's control circuit. The physical mounting and terminal pattern must align with the existing bracket and wiring. Measure the dimensions and compare the connector arrangement to ensure a proper fit. Always inspect the high-voltage ignition cables for damage before installation, as a faulty cable can mimic a transformer failure.

Common failure modes for ignition transformers include internal short circuits, open windings, or insulation breakdown. Symptoms may include no spark at the electrode, intermittent ignition, or burner lockout after the safety time. Check the primary voltage supply and the condition of the ignition cables. If the transformer is suspected, test the secondary output with a suitable high-voltage probe.
