Kromschroder Ignition transformer 84391045

The Kromschroder ignition transformer 84391045 is a device designed to generate a stable high-voltage spark for igniting gas and oil-fired burners. It operates with a supply voltage of 230 V and a frequency of 50 Hz, producing a secondary voltage of 7.5 kV and a secondary current of 12 mA. The transformer has a power consumption of 100 W and a duty cycle of 100%. It complies with the Machinery Directive 2006/42/EC.

Ignition transformers of this type are selected by matching the supply voltage, secondary voltage, and current ratings to the burner's requirements. The mounting form and dimensions must be compatible with the existing bracket or enclosure. Before ordering, verify the frequency (typically 50 or 60 Hz) and ensure the duty cycle meets the application's needs. Installation involves disconnecting power, removing the old unit, and connecting the new transformer according to the wiring diagram.

Common failure modes include no spark, weak spark, or intermittent ignition. This can result from internal component failure, insulation breakdown, or overheating. Check for visible damage, carbon tracking, or burnt connections. Measure the secondary voltage and current with appropriate test equipment to confirm output. Also inspect the primary supply voltage and wiring for loose connections.
