China manufacturer of magnetic ballasts for metal halide flood lights & hps flood lights

Sodium lamps ignitor automatic protection function. The original ignitor pulse to continue to impact the high pressure sodium lamp damaged ballast and trigger, the trigger soon damage. The utility model overcome this drawback, the effective protection of the trigger when the open circuit of the high pressure sodium ballasts, Do not autoclave the impact pulse. The utility model by the threshold voltage sampling control, fluctuations in voltage sampling control, automatic sampling control and high-voltage pulse generator circuit composed. , Less components, ignitor sensitivity, low cost, and great practical significance.
