Danfoss Electronic high voltage ignition transformer 052F4044

The Danfoss 052F4044 is an electronic high voltage ignition transformer designed for use in burner systems. It operates with a supply voltage of 230 V and a frequency of 50 Hz, providing a secondary voltage of 12 kV and a secondary current of 40 mA. This transformer is specifically fitted for the Danfoss EBI4 1P burner control. It steps up the mains voltage to generate a spark at the ignition electrode during the ignition sequence, as commanded by the burner control.

When selecting an ignition transformer of this type, ensure the primary voltage, secondary voltage, and secondary current match the burner system's requirements. The mounting form and terminal type must be compatible with the existing setup, and the connector pattern for the ignition cable should align. Verify the duty cycle to ensure it suits the ignition frequency. Compare these specifications with the original part before ordering.

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 a weak spark. Check the ignition cable for cracks or hardening, as a faulty cable can leak voltage to earth and mimic transformer failure. Also, inspect the transformer for signs of overheating or physical damage.
