Features: 
 ■ German Patent saving technology, high saving rate. 
 ■ automatic online detection voltage, current, automatic adjustment of power, protection switching and switching electric lamps normal state. 
 ■ Installation is simple, direct connections are at the lamp post lighting electrical metering instrumentation wire switch before. 
 ■ Intelligent integrated testing, to prevent voltage fluctuations, extended lamp life, do not increase the total harmonic circuit. 
 ■ safe "bypass" devices, security lighting does not affect the result of failure of the device to work properly, if the machine fails, automatically jump to the normal power system operation.
