ldsolar Sky Dream series PWM solar charge controller
Sky Dream Series (SD in short) is our newly designed PWM solar controllers. Its specialty lies in the inner 32 bits CPU, which enables the controllers to work faster and more stable. Besides, our unique black&Red big terminals design facilitate your connection in real application. It can be applied in the solar system which has higher
standard over the stability and reliability.

Design
Auto temperature compensation
The controller adopts asymmetrical design, and the LCD screen is located at the golden section, with a harmonious proportion and beautiful appearance.
USB
Free USB Charging
Support the maximum 1A charging current, charge your mobile device faster
10A / 20A with 2 USB ports, 30A / 40A with 1 USB port
We also supply 10A / 20A with 4USB models
Main control chip
ARM architecture, high-quality 32-bit main control chip , improve charging efficiency comprehensively.
Make your system more stable and efficient, the main control chip adopts STMicroelectronics, and the other components adopt Samsung and Fenghua Hi-tech components to ensure the stability and life of the controller. The running program of the upgradeable frame structure guarantees the low loss of the controller and makes it more efficient.
Heat dissipation
Distinctive heat dissipation character
This time, we also made a brand-new upgrade design for the SD series heat dissipation system, and the back MOS tubes are evenly distributed.
While ensuring a stylish and simple appearance, the heat dissipation is further improved.
