◆DAK系列是一款通用型的直流扳機調速開關，集成防塵(chen)和機械剎(cha)車接點，內部帶換向結構，應用于各類直流充電(dian)式(shi)手(shou)持(chi)電(dian)動工具，如：充電(dian)式(shi)電(dian)鉆、充電(dian)式(shi)電(dian)錘、充電(dian)式(shi)螺絲起子、充電(dian)式(shi)沖擊(ji)扳(ban)手(shou)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(gou)緊(jin)湊效率高，大面(mian)積的固定式(shi)散(san)熱片為(wei)開關的安(an)裝提供方便。開關內(nei)部為(wei)單極(ji)常開帶直通接點結構(gou)，通過改變輸入脈(mo)沖的占空比來控制場效應管的輸出電壓，而實現電子(zi)調速功能(neng)。
◆開(kai)關(guan)(guan)輸出端(duan)的平均電壓(ya)為總電壓(ya)的8- 50%至(zhi)8- 90%，也可(ke)以按(an)客戶(hu)要求進(jin)行定制(zhi)，開(kai)關(guan)(guan)按(an)到底由直通接(jie)點接(jie)至(zhi)電池端(duan)電壓(ya)。
◆可選帶以下(xia)功能(neng)或附件(jian):
→外(wai)置MOS管(guan)→智能調(diao)速功能，可帶軟啟動、欠壓保護(hu)、過(guo)流保護(hu)、電池過(guo)溫(wen)保護(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(ru)端(duan)/輸出端(duan) Input side/Output side:
→焊接端子(zi) Solder terminal
