Introduction:
Solar + LED driver series controller is built-in high performance constant current source. With the high efficiency, high power density, multi-lamp beads tandem drive, multi-level dimming technology have been walking in the forefront of the industry. SR-SD series controllers with high performance LED special drive IC and high speed MCU union control plan, make it better than with the PWM adjust or single MCU analog constant current source in term of LED constant current source and multitasking.
The superiority:
1.high-speed dynamic response;
2.fast control loop;
3. Precise slope compensation;
4. Smart soft start device;
5. precise current control;
6. transient failure protection;
7. Low current ripple;
8. High reliability;
The controller is designed for solar Street light and yard lamp which require dimming. With the innovative technology combine with the solar controller and constant current source in one, and with the advanced pulse width modulation charging ways enables the system charging and discharging management to obtain the most radical optimization. Make the system cost reduce, and increase the system flexibility. The product adopts advanced PWM dimming technology makes LED color temperature excellent, even in the different brightness, LED color cast also can achieve strict uniform. Because of its high power density design, SR-SD series products can provide greater output power.
Four time intervals dimming technology allow LED to work under different power, moreover, each group Power working time can be set free to make the load control more intelligent and flexible.
