combined with thermal shutdown and automatic restart protects the device agai nst overload. The current limitation threshold is aimed at detecting the 21W/12V st andard bulb as an overload f ault. The device detects open load condition both in on and off state. Output shorted to V the off state. Device automatically turns off in case
