Switching Spark Gaps (SSG)
Description
The principle of gas discharge is used not only for overvoltage
protection but also in switching applications. Unlike surge
arresters, switching spark gaps are active components that work
reliably even after igniting hundreds of thousands of times.
RUILON 2RK-8 series Switching Spark Gaps(SSG) can be used
in all applications where high voltage pulses are generated, for
example to ignite modern high-pressure gas discharge lamps
such as xenon lamps in automotive headlights. Ignition
performance is determined to a large degree by the properties of
the switching component. An extremely fast switch is called for,
which operates virtually without loss and with high insulation
resistance in the non-conducting state. It should also be as
compact as possible, rugged, highly reliable, and capable of
operating over a wide temperature range.
