Brahma Ignition transformer T11/M 15093061

The Brahma ignition transformer T11/M (SKU 15093061) is a spark transformer designed for burners using liquid or gaseous fuels. It operates with a supply voltage of 220 V at 50 Hz, delivering a secondary voltage of 9 kV and a secondary current of 20 mA. The transformer has a duty cycle of 33% in 3 minutes, a power consumption of 240 W, and an input effective current of 1.1 A. It features a centrally grounded secondary winding, polyester resin insulation, and a shell-shaped magnetic circuit. The unit is equipped with a screw terminal for high-voltage connection and must be securely grounded. It measures 150x101x100 mm, weighs 2 kg, and has an IP00 protection rating.

When selecting an ignition transformer of this type, ensure that the supply voltage, frequency, and secondary voltage/current ratings match the burner's requirements. The mounting system and connection type (e.g., screw terminal) must be compatible with the existing installation. Verify the physical dimensions and weight to ensure proper fit. The transformer can be installed in any position, but the grounding must be securely connected to a single grounding center. Always follow national and European safety standards (e.g., EN 60335-1 / EN 60335-2-102) during installation.

Common failure modes for ignition transformers include insulation breakdown, which can cause short circuits or loss of spark. Symptoms may include the burner failing to ignite, intermittent ignition, or visible arcing or burning on the transformer casing. Check for signs of overheating, cracked insulation, or loose connections. If the transformer is not producing the required high voltage, test the secondary output with a suitable probe and inspect the primary supply for correct voltage and current.
