◆DAK系列是一款通用型的直流扳机调速开关,集成防尘和机械刹车接点,内部带换向结构,应用于各类直流充电式手持电动工具,如:充电式电钻、充电式电锤、充电式螺丝起子、充电式冲击扳手等。
◆DAK series are one general type DC variable speed trigger switches,integrated dustproof, mechanical brake contact and reversing box, commonly for used in DC cordless portable power-tools such as: Cordless Drills, Cordless Screw Drivers, Cordless Rotary Hammers, Cordless Impact Wrenches, etc.
◆本开关结构紧凑效率高,大面积的固定式散热片为开关的安装提供方便。开关内部为单极常开带直通接点结构,通过改变输入脉冲的占空比来控制场效应管的输出电压,而实现电子调速功能。
◆开关输出端的平均电压为总电压的8 - 50%至8 - 90%,也可以按客户要求进行定制,开关按到底由直通接点接至电池端电压。
◆可选带以下功能或附件:
→外置MOS管→智能调速功能,可带软启动、欠压保护、过流保护、电池过温保护
◆The switches combine compact size with high performance, a wide scope of heat sink for MOSFET and further options provide easy to mount solutions. They employ SPST-NO with by-pass contact, integrated PWM (Pulse Width Modulated) electronics in valrious dimensions.→External MOSFET version
→Trigger covered with rubber
→Auxiliary LED and wires
→Auxiliary wire for temperature test
→Multi-function, optional soft start, under-voltage protection, over current protection, battery temperature protection
◆输入端/输出端 Input side/Output side:
→焊接端子 Solder terminal
