FAQ

What does '100% ED' mean for this transformer?

'100% ED' stands for 100% Einschaltdauer, or 100% duty cycle in English. This means the transformer is designed and rated for continuous operation without needing a cool-down period, making it suitable for applications that require a constant or frequent ignition spark.

Is this transformer suitable for both gas and oil burners?

Yes, the Honeywell TQO32.A27 is a versatile ignition transformer designed for use with both gas and oil burner systems. Its high-voltage output of 2 x 7.5 kV is effective for igniting either fuel type reliably.

Can I replace a transformer with a lower secondary current (e.g., 20mA) with this 40mA model?

While physically possible, it is not recommended without consulting the burner manufacturer's specifications. The ignition current is a critical parameter for stable ignition and flame safety. Using a transformer with double the current (40mA vs 20mA) could affect electrode wear and ignition performance. Always match the replacement part's specifications to the original.
