Abstract

This invention discloses a protecting device of an electronic stabilizer. This protecting device is used to protect an electronic stabilizer system. This protecting device is activated when current overload is detected. When a system is in operation and the current transformer (CT) on a lamp circuit detects that the signal level is lower than a safety value, the protecting device is not activated. When the CT detects that the signal level is higher than a safety value, it indicates that the current loaded in the stabilizer is overloaded, so that the protecting device is activated to reduce the load of the operation system. This invention can prolong the service life of a lamp and increase the safety of a lamp.
