详细内容
vs80b系列内置锂电池保护功能电子调速开关 
型号：vs80b 
电气参数：dc 25.1a 24v
电池额定电压：14.4～24v
描述：vs80b系列是高度集成同时尺寸非常紧凑的内置保护功能调速开关,它集成了锂电池低压保护、过流保护、调速、刹车、换向和中间位置锁定功能。此外，开关还具有3种速度模式选择功能，用户可依据不同的应用要求来选择合适的速度模式，轻松实现在不同操作要求间的切换。
开关高度集成与尺寸极其紧凑的特点为机壳安装设计提供了非常大的便利和优势，使得它很方便应用于各种电动工具与其他电器产品。
特征：
1. 过流保护功能;
2. 低压保护功能;
3. 无级调速功能，电子直通功能；
4. 机械刹车功能;
5. 开关正极导通，并采用复合触点结构，能够更好的适应大电流的冲击;
6. 外接轻触开关，具有多种速度模式供选择，并通过led来显示所选的速度模式;
7. 机械换向功能，换向拨杆处于中间位置时锁定，断开；
8. 可外接工作照明led灯, 且led有延时和逐渐熄灭功能;
9. 通过ul,cul安全认证（25.1a 24v）；
10.可增加电池温度保护(高温保护与低温保护)连接检测功能。
应用：各种锂电池电器或工具产品，例如电动起子，电钻，冲击扳手，家用电器等.
