Honeywell ET402A ignition transformer

Honeywell ET402A ignition transformer. Original dual-output pulse transformer for gas and oil burners. The Honeywell ET402A ignition transformer is a specialized electronic device (electronic high-voltage pulse generator) designed for reliable ignition of gas, oil, and dual-fuel burners. Model ET402A (also known in warehouse systems as 534.823.006) converts mains voltage 230 V into two high-voltage pulses of 2 x 7 kV (or 14 kV between terminals) required 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 This transformer belongs to the ET (Electronic Transformer) series and is a modern electronic alternative to outdated electromechanical models (e.g., ZT930, ZT931). Thanks to pulsed high-frequency technology, it provides a more powerful spark with lower power consumption and low electromagnetic interference. Purpose and application: Honeywell ET series ignition transformers are designed for installation in industrial and domestic burner devices. Model ET402A has two high-voltage outputs and is intended for igniting a pilot or main burner in systems requiring two ignition electrodes. Typical applications: Gas burners: for ignition of natural gas or liquefied petroleum gas (propane-butane). Oil burners: for ignition of diesel fuel or fuel oil. Dual-fuel burners: for equipment operating on gas and liquid fuel. Gas heating boilers: as part of central heating boiler automation. Industrial burner devices: at heat generation facilities and industrial furnaces. The device can be installed directly under the control unit.
