1. Overview  

Thank you for selecting the

 

NSC1210D series common positive solar charge controller. The NSC1210D 

controller is a PWM charge controller with built in LCD display that adopts the most advanced digital technique. 
The multiple load control modes enable it can be widely used on solar  home  system, traffic signal, solar street 
light, solar garden lamp, etc. The features are listed below :  

 

3-stage intelligent PWM charging : Bulk, Boost/Equalize, Float  

 

Support 3 charging options : Sealed, Gel, and Flooded  

 

LCD display design, dynamically displaying device's operating data and working condition  

 

Multiple load control modes  

 

Energy statistics function  

 

Battery temperature compensation function  

 

Extensive Electronic protection
