◆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(xie)剎(cha)車接點，內部(bu)帶換(huan)向結構(gou)，應(ying)用(yong)于各(ge)類直流充(chong)(chong)(chong)電(dian)式(shi)(shi)手持電(dian)動工具(ju)，如：充(chong)(chong)(chong)電(dian)式(shi)(shi)電(dian)鉆、充(chong)(chong)(chong)電(dian)式(shi)(shi)電(dian)錘、充(chong)(chong)(chong)電(dian)式(shi)(shi)螺(luo)絲起子、充(chong)(chong)(chong)電(dian)式(shi)(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(kai)關結構緊湊效率(lv)高，大面積的(de)固定(ding)式散熱片為開(kai)關的(de)安裝提供方便。開(kai)關內部為單(dan)極常開(kai)帶直通接點(dian)結構，通過改變(bian)輸入脈沖的(de)占(zhan)空比來控制場效應管的(de)輸出電壓(ya)，而實現(xian)電子調速功(gong)能。
◆開關(guan)輸出端的(de)平均電壓為總(zong)電壓的(de)8 - 50%至8 - 90%，也可以按客戶要求進行定制，開關(guan)按到底由直通接(jie)點(dian)接(jie)至電池端電壓。
◆可選帶以(yi)下功(gong)能(neng)或附件:
→外(wai)置(zhi)MOS管→智能調速功能，可(ke)帶軟啟動、欠壓保(bao)護、過流保(bao)護、電池過溫保(bao)護
◆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 Solder terminal
