Brahma Ignition transformer T11/MC 15096001

The Brahma Ignition transformer T11/MC 15096001 is designed for use in burners operating on liquid or gaseous fuels. It operates at a supply voltage of 220 V and a frequency of 50 Hz, with a power consumption of 240 W. The transformer provides a secondary current of 20 mA and has a duty cycle of 33% in 3 minutes. It features one pole, measures 101 mm in length, 80 mm in width, and 82 mm in height, with a net weight of 3.5 kg. The insulation is made of polyester resin, and the insulator material is 30% PBT glass fiber. The recommended spark distance is 3–5 mm, and the standard power cable length is 550 mm. The protection class is IP00.

When selecting a replacement ignition transformer of this type, ensure that the supply voltage, frequency, and power consumption match the burner's electrical specifications. The physical dimensions and mounting method must be compatible with the existing installation. The high-voltage cable connection type (screw terminal or cylindrical terminal with a diameter of 4 mm or 6.3 mm) should be verified to match the existing wiring. The recommended spark distance and duty cycle must be suitable for the burner's operational requirements.

Common failure modes for ignition transformers of this kind include internal short circuits or open windings, leading to a lack of spark or weak spark at the electrodes. This may result in the burner failing to ignite or experiencing intermittent flame loss. Check for visible damage, overheating, or signs of electrical arcing on the transformer casing. Measure the input and output voltages with a multimeter to confirm proper operation.
