Brahma Ignition transformer TB1LVCA 15911026

The Brahma TB1LVCA ignition transformer, SKU 15911026, is an electronic component designed for forced-draft gas burners and burners using light or heavy fuel. It operates on a supply voltage of 220–240 V at 50–60 Hz, delivering a secondary voltage of 17 kV and a secondary current of 26 mA. With a duty cycle of 50%, it consumes 35 W of power. The transformer features a compact plastic housing, a ferritic core, and a built-in varistor for surge protection. It measures 106 mm in length, 90 mm in width, and 44.2 mm in height, with a net weight of 0.53 kg.

When selecting an ignition transformer of this type, verify that the supply voltage, secondary voltage, and current ratings match the burner's requirements. Ensure the physical dimensions fit the mounting space and that the high-voltage output connector type (e.g., screw terminal) is compatible with the ignition cable. The duty cycle must be suitable for the burner's operational pattern. Always compare the electrical specifications and mounting form with the original part before ordering.

Common failures in ignition transformers include internal short circuits or open windings, often caused by moisture ingress or voltage surges. Symptoms may include no spark at the electrode, weak or intermittent spark, or the burner failing to ignite. Check for visible damage, measure the secondary voltage with a suitable probe, and inspect the varistor for signs of overvoltage damage.
