High Voltage (HT) ignition power units represent the cheapest ignition solution available in our range, given the simplicity of the structure - the spark plug is often a simple ceramic insulated electrode.
These simple devices generate an electric arc from the output of an ignition transformer (at 6 or 8 kV) with low power (150/300 W).
They are suitable to ignite mainly gas fuels, as they do not well tolerate high thermal stresses, humidity and combustion residuals between the electrode terminals.
