Description
The Brahma TB2SVCAF ignition transformer (SKU 15910564) is a high-frequency generator that boosts voltage to 15 kV for ignition in gas and oil burners. It features a plastic housing, a ferritic core, and two high-voltage outputs with screw connectors for ignition cables. The transformer includes a built-in EMC filter and a varistor for surge protection, and it operates within a temperature range of -10 to +60 °C.
Choosing and fitting
When selecting an ignition transformer of this type, ensure the secondary voltage and connector type match the burner's requirements. Verify the mounting dimensions and the length of the power cable to fit the existing setup. The transformer should be installed with proper clearance for high-voltage connections and secured to prevent vibration.
Signs of failure
Common failure modes for ignition transformers include internal short circuits or open windings, often caused by moisture ingress or overheating. Symptoms may include weak or no spark at the electrodes, intermittent ignition, or tripping of the burner's safety lockout. Check for visible damage, measure the secondary voltage with a suitable probe, and inspect the high-voltage cables for cracks or corrosion.
