Fida Ignition transformer 26/35 50% IS 230V ENSB31

The Fida ignition transformer SKU ENSB31 (model 26/35 50% IS 230V) is a step-up transformer that provides high-voltage spark for gas and liquid fuel burners. It is rated for 230 V supply and operates only during the ignition phase, under control of the burner control box. Once the flame is established, the transformer is de-energised.

For a replacement ignition transformer of this type, confirm that the primary voltage matches the burner supply (230 V is common, but 110 V and 24 V versions exist). The secondary voltage and current, the duty cycle (on-time relative to the full cycle), mounting arrangement, and terminal/connector pattern must be compatible with the existing unit and the burner control. The high-voltage cable connector must fit the electrode lead. Ignition cables must be silicone-insulated to withstand high voltage and heat near the combustion head; a cracked or hardened cable can leak the spark to earth and mimic a failed transformer.
