constant current solar streetlight controller, solar controller
constant current solar streetlight controller has light and time control. It is equipped with high precision Boost LED constant current source which can save the power. Ideal for public lighting area, such as street light, path way, garden lights, parking area, bus station etc.
Use optimized PWM charging, four period of dimming control, can set the dimming time flexibly.
With separated temperature detected circuit, with high precision temperature compensation function.
Can set four period operation mode and adjust the output powerflexibly from 10% to 90%.
Double digit LED display, function and parameter settings can operate in one interface.
Use SMT chip production technology, industrial class chip, advanced technology, quality assurance.
Equipped with high precision Boost LED constant current source, with intuitive working status indicators..
