◆DAK系列是一款通用型的直流扳機調速開關，集成防塵和機(ji)械剎車接點(dian)，內(nei)部(bu)帶(dai)換向結構，應用于(yu)各類直流充(chong)(chong)(chong)電式手持電動工具，如：充(chong)(chong)(chong)電式電鉆、充(chong)(chong)(chong)電式電錘(chui)、充(chong)(chong)(chong)電式螺絲起(qi)子、充(chong)(chong)(chong)電式沖(chong)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(ben)開(kai)關(guan)結(jie)構(gou)緊湊效率高，大面積的(de)固定式(shi)散熱片為(wei)開(kai)關(guan)的(de)安裝提(ti)供方便(bian)。開(kai)關(guan)內部為(wei)單極常開(kai)帶直通接點結(jie)構(gou)，通過改變輸入(ru)脈(mo)沖的(de)占空比來控制(zhi)場效應管的(de)輸出電壓，而實現電子調速功能(neng)。
◆開(kai)關(guan)輸出端的(de)平(ping)均(jun)電壓(ya)為總(zong)電壓(ya)的(de)8- 50%至8- 90%，也可以按(an)客戶要求進行定制，開(kai)關(guan)按(an)到底由直通(tong)接(jie)點(dian)接(jie)至電池端電壓(ya)。
◆可(ke)選帶以下功能或附件:
→外(wai)置MOS管(guan)→智能調(diao)速(su)功能，可帶軟(ruan)啟動(dong)、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(chu)端(duan) Input side/Output side:
→焊接端子 Solder terminal
