Transformateur d'allumage Honeywell « ET401A »

Ignition transformer Honeywell ET401A. Original high-voltage pulse transformer for burner devices. Ignition transformer Honeywell ET401A is a specialized electronic device (electronic high-voltage pulse generator) designed for reliable ignition of gas and dual-fuel burners. Model ET401A (also known in warehouse accounting systems as 534.823.004) converts standard mains voltage 230 V into a high-voltage pulse of 14 kV, necessary to create a stable spark between ignition electrodes. This transformer belongs to the ET (Electronic Transformer) series and is a modern electronic alternative to outdated electromechanical models (e.g., ZT930). Thanks to pulsed high-frequency technology, it provides a more powerful spark with lower power consumption and significantly lower electromagnetic interference. Purpose and application: Honeywell ET series ignition transformers are designed for installation in industrial and domestic burner devices. Model ET401A has one high-voltage output and is intended for igniting a pilot or main burner in systems requiring only one spark point. Typical applications: Gas burners: For ignition of natural gas or liquefied petroleum gas (propane-butane). Gas heating boilers: As part of central heating boiler automation. Industrial burner devices: In heat generation facilities and industrial furnaces. Automatic combustion control systems: Integration with burner control boxes. The device can be installed directly under the burner control box thanks to compatible mounting holes and compact dimensions.
