Hid ballast

Listing ID #3606857

HID lamp ignitors provide a brief, high voltage pulse or pulse train to breakdown the gas between the electrodes of an arc lamp. Pulses can range from several hundred volts to 5KV.Typical durations are in the μ seconds range. They are usually timed to coincide with the peak of OCV. If they are timed too early or too late, lamps may not start reliably.There are three basic ignitors circuits in wide use. The simplest is a capacitor in series with a voltage sensitive switch that connects across the output of a lag ballast.
