低压型LED产品一般设计电压12V-36V,每个回路LED数量3-6个串联，用电阻降压限流，每个回路电流20mA以下。一个LED产品由多个回路的 LED组成，优点是低压，结构简单，容易设计；缺点是：产品规模大时电流很大，需要配置低压开关电源。

由于产品的缺点所限，低压不可能远距离输电，都是局限于体积不大的产品上，如招牌文字、小图案等。根据这个特点，控制器设计规格：12V的选用75A/30V MOS功率管控制，输出电流8A/路；24-36V选用60A/50V MOS功率管控制，输出电流5A/路。

用户可以根据以上规格选定控制器的路数，跳变的可以选购NE20低压系列、渐变的选购NE10低压系列控制器即可。注意LED的必须是共阳(+)较连接法，控制器控制阴(-)较，控制器不包括低压电源
