Fida Ignition transformer 28/35 PML ENPLD3

The Fida Ignition transformer 28/35 PML ENPLD3 is a component used in burner ignition systems. It steps up the mains voltage to a level sufficient to create a spark at the ignition electrode. The transformer operates only during the ignition period, controlled by the burner control. It is connected between the burner control and the ignition electrode, with a high-voltage silicone-insulated cable carrying the output. This model is designed for use with Fida 28/35 PML equipment.

When selecting a replacement ignition transformer of this kind, key parameters to match include primary voltage, secondary voltage and current, duty cycle, mounting style, terminal type, and cable connector pattern. Primary voltages are commonly 230 V, but 110 V and 24 V versions exist. The duty cycle must match the burner's cycle to avoid overheating or ignition failure. Always verify that the replacement matches the original in primary voltage, mounting configuration, and terminal layout, as physical interchangeability does not guarantee electrical compatibility.

A common failure mode for ignition transformers of this kind is a damaged ignition cable. The silicone insulation can harden or crack over time, causing the spark energy to leak to earth, which mimics a faulty transformer. This can result in failure to ignite or intermittent operation. Before condemning the transformer, check the cable and its connections for damage.
