Cofi Ignition transformer TRS1030/3

The Cofi Ignition transformer TRS1030/3 is a two-pole, high-voltage unit designed for gas burners. It operates on a 230 V supply at 50 Hz and features two high-voltage outputs. This Italian-made transformer provides a bipolar output, generating a symmetrical spark between two ignition electrodes for ignition of medium and large gas burners.

When selecting an ignition transformer of this type, ensure the primary voltage (e.g., 230 V) and frequency match the burner's control circuit. Verify the number of high-voltage outputs and the connector pattern for the high-voltage cables. Mounting arrangement and terminal type must also be compatible with the existing installation. Measure the physical dimensions and compare with the original part before ordering.

Typical failures include no spark or a weak spark, often caused by internal breakdown or damaged high-voltage cables. The burner may fail to ignite, leading to a lockout condition. Check the transformer for visible damage, and test the high-voltage output with a suitable probe. Also inspect the ignition cable for cracks or hardening, as these can leak spark to ground and mimic transformer faults.
