TAR - Burner ignition transformers
TAR are specific burner ignition transformers for the ignition of gas and fuel oil burners. They generate a spark that ignites industrial burners.
Description
The TAR series burner ignition transformers are designed for the electric ignition of industrial gas, diesel, and oil burners, generating the high‑voltage spark needed to initiate combustion. They comply with EN61558‑2‑3 and Directive 2014/35/EU regarding safety for ignition transformers.
The burner ignition transformers range includes four active models—TAR‑10, TAR‑11, TAR‑12, and TAR‑13—each suited to different ignition and duty‑cycle requirements.
TAR‑10 provides 8 kV at 20 mA, supports ignition and flame detection using a single electrode, and offers a 19% duty cycle at 35°C.
TAR‑11 also outputs 8 kV but is intended only for ignition, with an improved 45% duty cycle.
TAR‑12 is an electronic transformer delivering 10 kV at 20 mA, compact and lightweight, suitable for ignition and detection in applications requiring higher frequency (10 kHz).
TAR‑13 provides 6 kV at 10 mA and supports continuous operation (100% duty cycle), making it suitable for burners requiring a constant spark. All models use self‑threading HV cable connections and silicone HV cables up to 1 m (5 m maximum for winding models).
Functionally, the transformer energizes the ignition electrode; the high‑voltage discharge arcs to the burner mass, igniting the fuel. Proper selection depends on the electrode configuration (ignition only or combined ignition/detection) and required duty cycle. Duty cycle limitations ensure the transformer does not overheat: operational time within a 3‑minute cycle must respect each model’s specified percentage.
Installation guidelines require placement away from heat, magnetic fields, and metal masses to prevent unwanted arcing. HV cables (VS or GVR) must be routed in open air, kept short, and separated from other conductors. The HV output must always be connected before powering the transformer to avoid severe damage.
Maintenance includes checks of cable integrity, arc intensity, conductor tightening, and electrode condition. Transformers must be replaced if damaged or no longer functioning correctly.
