Brahma Ignition transformer 15000161

Brahma Ignition transformer 15000161 is a column-type ignition transformer with 2 primary and 2 secondary windings, insulated with high-insulation polyester resin. It operates at a supply voltage of 230 V and 50 Hz, with a secondary voltage of 6.5 kV and a secondary current of 33 mA. The transformer has a peak voltage of 2 x 11 kV, an ignition current of 35 mA, and a power consumption of 460 VA. It features a duty cycle of 33% in 3 minutes, an input effective current of 2.1 A, and is suitable for high thermal output burners and steam boilers. The unit includes an ignition cable, has a screw connector of ø2.5 mm, and weighs 3.5 kg with dimensions of 10.1x8x15 cm.

Ignition transformers of this type are selected by matching the supply voltage, secondary voltage, and mounting system to the burner's requirements. The transformer must have the correct electrical characteristics (e.g., voltage, current, duty cycle) and physical dimensions to fit the burner's mounting bracket. Different mounting systems exist, such as T8 and T8/G, so verify the mounting type and dimensions before ordering. Ensure the ignition cable length and connector type are compatible with the electrode assembly.

Common failures include shorted or open windings, insulation breakdown, and cracked or damaged connectors. Symptoms may include no spark, weak spark, or intermittent ignition, leading to burner lockout or failure to start. Check for visible damage, measure primary and secondary voltages, and inspect the ignition cable and electrode gap for wear or corrosion.
