Brahma Ignition transformer TD1STCSF 15910686

The Brahma TD1STCSF ignition transformer (SKU 15910686) is a high-frequency electronic device that steps up the supply voltage of 220–240 V to a peak output of 15 kV, with a secondary current of 45 mA. It operates continuously with a 100% duty cycle and consumes 25 W (25 VA). The transformer features an integrated EMC filter, built-in short circuit protection, and a ferritic core, and is designed for gas and liquid fuel burners in domestic, commercial, and industrial installations. It has one high-voltage output, a recommended spark distance of 3–5 mm, and a maximum ignition cable length of 1.5 m. The unit is ultra-compact, lightweight (360 g), and can be mounted in any position, with an ingress protection rating of IP00.

When selecting an ignition transformer of this type, ensure the supply voltage and frequency (e.g., 220–240 V, 50–60 Hz) match the burner's electrical system. The secondary voltage and current (e.g., 15 kV, 45 mA) must be compatible with the electrode gap and ignition requirements. Check the mounting arrangement and connecting systems, as these transformers can be installed in any position and offer various mounting options. Verify the required protection class (e.g., IP00) and ensure the valve body is grounded according to safety standards. The length of the ignition cable and power cable must be sufficient for the installation.

Common failures in ignition transformers of this kind include internal short circuits or open windings, leading to no spark or weak spark at the electrodes. The burner may fail to ignite or may shut down intermittently. Check for visible damage, overheating, or a burnt smell. Measure the output voltage with a suitable high-voltage probe to confirm the transformer is producing the expected peak voltage. Also inspect the ignition cable and electrode gap, as these can cause similar symptoms.
