◆DAK系列是一款通用型的直流扳機調速開關，集(ji)成防(fang)塵和機械剎車(che)接點，內(nei)部帶換向結構，應用于各類(lei)直流充(chong)(chong)電式(shi)手持(chi)電動工具，如：充(chong)(chong)電式(shi)電鉆、充(chong)(chong)電式(shi)電錘、充(chong)(chong)電式(shi)螺絲起子、充(chong)(chong)電式(shi)沖(chong)擊扳(ban)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(kai)關(guan)結(jie)構緊湊(cou)效率高，大面積的(de)固定式(shi)散(san)熱片為開(kai)關(guan)的(de)安(an)裝提供方便。開(kai)關(guan)內部為單極常開(kai)帶直通(tong)接點結(jie)構，通(tong)過改變(bian)輸(shu)入脈沖的(de)占空比來控(kong)制場效應管的(de)輸(shu)出電(dian)壓，而(er)實現(xian)電(dian)子調速(su)功能。
◆開關輸出端(duan)的(de)(de)平均電(dian)壓為(wei)總電(dian)壓的(de)(de)8 - 50%至8 - 90%，也可以按客戶要求進行定制，開關按到(dao)底由直(zhi)通接點接至電(dian)池端(duan)電(dian)壓。
◆可選(xuan)帶(dai)以下功(gong)能或附件(jian):
→外置MOS管→智能(neng)調速(su)功能(neng)，可帶軟啟動、欠壓(ya)保(bao)護(hu)、過(guo)流(liu)保(bao)護(hu)、電池過(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(zi) Solder terminal
