Brahma Ignition transformer T17/N 15453001

The Brahma T17/N ignition transformer (SKU 15453001) is designed for use in burners operating on liquid or gaseous fuels. It operates with a supply voltage of 220 V at 50 Hz, consuming 140 W. The transformer provides a secondary voltage of 4–4 kV with a secondary current of 15 mA, and features a 100% duty cycle. It has two poles, a net weight of 2 kg, and is constructed with a PBT body containing 30% fiberglass, with polyester resin insulation. The recommended spark distance is 3–5 mm, and the standard power cable length is 550 mm. The secondary winding is center grounded, and the RF shield must be securely grounded. The transformer can be mounted in any position and uses a screw terminal for electrical connection.

When selecting an ignition transformer of this type, ensure that the supply voltage, frequency, and power consumption match the burner's electrical specifications. Verify the secondary voltage and current requirements, as well as the duty cycle, to ensure compatibility with the ignition system. The mounting system may vary; check the model designation for specific mounting features, and confirm the electrical connection type (e.g., screw terminal) matches the existing wiring. Measure the physical dimensions and weight to ensure proper fit within the equipment.

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 a weak spark. Check for visible damage to the body or cables, and test the secondary voltage and current with appropriate equipment. Ensure the ground connections are secure, as poor grounding can lead to erratic operation or interference.
