◆DAK系列是一款通用型的直流扳機調速開關，集成防塵和機械(xie)剎車接點(dian)，內部帶換向結構，應用于各類直流(liu)充(chong)電式(shi)手持電動工具，如：充(chong)電式(shi)電鉆(zhan)、充(chong)電式(shi)電錘、充(chong)電式(shi)螺絲起子、充(chong)電式(shi)沖擊扳手等。
◆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.
◆本開關結構緊(jin)湊效率(lv)高，大面(mian)積(ji)的固定式(shi)散熱片為(wei)開關的安(an)裝提供方便。開關內部(bu)為(wei)單極常開帶直通接點結構，通過改變輸入脈沖的占空比來控制場效應管(guan)的輸出電壓，而實現(xian)電子(zi)調速功(gong)能。
◆開關(guan)輸出端(duan)的平均電(dian)壓(ya)為總電(dian)壓(ya)的8 - 50%至(zhi)8 - 90%，也(ye)可以按客戶要求進行定制，開關(guan)按到底由(you)直通接(jie)點接(jie)至(zhi)電(dian)池端(duan)電(dian)壓(ya)。
◆可(ke)選(xuan)帶以下功(gong)能(neng)或附件:
→外置(zhi)MOS管→智能(neng)調速功能(neng)，可帶(dai)軟(ruan)啟動、欠壓保(bao)護(hu)、過(guo)流保(bao)護(hu)、電(dian)池過(guo)溫保(bao)護(hu)
◆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
◆輸入端/輸出(chu)端 Input side/Output side:
→焊接端(duan)子 Solder terminal
