Brahma Ignition transformer TA1SVCAF 15910562

The Brahma TA1SVCAF ignition transformer (SKU 15910562) is a high-frequency electronic generator that produces a secondary voltage of 17 kV and a secondary current of 26 mA, with an ignition voltage range of 15–17 kV. It operates on a supply voltage of 220–240 V at 50–60 Hz, consuming 35 W. The transformer features a built-in EMC filter and varistor for electromagnetic interference suppression and voltage fluctuation resistance, and its electronic circuit and ferritic core are filled with polyester resin for protection against temperature fluctuations. It has a compact, shock-resistant plastic housing with dimensions of 106x87x63 mm and a net weight of 0.53 kg, and is designed for use in domestic and industrial burners fueled by gas, diesel, or fuel oil. This model replaces T8 series transformers and includes a standard power cable length of 560 mm.

When selecting an ignition transformer of this type, ensure the supply voltage, secondary voltage, and current ratings match the burner's requirements. The mounting form and dimensions must be compatible with the existing installation, and the number of high-voltage outputs (typically one) should correspond to the ignition electrode configuration. Check the duty cycle (e.g., 50%) to confirm it suits the burner's operating cycle, and verify the ingress protection rating (e.g., IP00) is acceptable for the environment. For replacement, compare the physical dimensions and mounting holes with the original unit, and confirm the connector type for ignition cables (e.g., screw type) matches.

Common failures of ignition transformers include internal short circuits or open windings, often caused by moisture ingress or overheating, leading to weak or no spark. Symptoms on the equipment include burner ignition failure, intermittent sparking, or a buzzing sound from the transformer. Check the secondary voltage with a suitable probe, inspect for visible damage or burn marks, and verify the primary supply voltage and connections. If the transformer is suspected, test it with a known good unit or measure resistance across windings to confirm continuity.
