Brahma Ignition transformer 15930030

The Brahma Ignition transformer 15930030 is a high-frequency electronic generator with a step-up transformer and ferritic core, producing a secondary voltage of 17 kV at 7 kHz. It operates on a 230 V, 50 Hz supply, consuming 23 W (23 VA) with a duty cycle of 100%. The transformer features a single contact, integrated EMC filter, built-in varistor, and short circuit protection. It is designed for compact installation in any position, with a recommended spark distance of 3–5 mm and a maximum ignition cable length of 1.5 m. The unit weighs approximately 250 g and complies with EN 61558-1:2005+A1:2009 and EN 61558-2-3:2010 standards, as well as directives 2006/95/EC and 2004/108/EC.

When selecting an ignition transformer of this type, ensure the supply voltage, frequency, secondary voltage, and current ratings match the burner controller requirements. Check the mounting dimensions and connection systems (e.g., single- or double-contact output, connector types) to fit the existing bracket and wiring. Verify the recommended spark distance and maximum ignition cable length for the application. The transformer can be installed in any position, but must be grounded and placed away from other cables to avoid interference.

Typical failures of such ignition transformers include internal short circuits or open windings, often caused by overheating or voltage surges. 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 with a multimeter, and inspect the spark gap and cable insulation for wear or corrosion.
