Cofi Ignition transformer TRS1020/1

The Cofi Ignition transformer TRS1020/1 is a bipolar ignition transformer with a supply voltage of 230 V and a secondary voltage of 10 kV. It operates at 50 Hz and features two poles. The transformer measures 140 mm in length, 86 mm in width, and 66 mm in height. It is designed for use in industrial and domestic gas burners and includes overload protection, vibration resistance, and high-temperature resistance. The transformer uses standard connectors and is silicone-insulated for the ignition cable.

When selecting an ignition transformer of this type, verify that the primary voltage (e.g., 230 V) and frequency match the burner's electrical supply. The secondary voltage and current must be compatible with the electrode gap and ignition requirements. Ensure the mounting dimensions and terminal arrangement fit the burner housing. Check the connection type for the high-voltage cable and confirm the duty cycle can handle repeated ignition periods.

Common failures include no spark or intermittent sparking, leading to burner shutdown or ignition failure. This can be caused by internal component breakdown, overheating, or damage from vibration. Check the ignition cable for cracks or hardening, as silicone insulation can degrade, causing spark leakage to earth. Also inspect the electrodes for wear or contamination, which can mimic transformer faults.
