◆DAK系列是一款通用型的直流扳機調速開關，集成(cheng)防塵和機械剎車接點，內(nei)部帶(dai)換向(xiang)結構，應(ying)用于(yu)各類直流(liu)充(chong)(chong)電式手(shou)持(chi)電動工具，如：充(chong)(chong)電式電鉆、充(chong)(chong)電式電錘(chui)、充(chong)(chong)電式螺(luo)絲起子、充(chong)(chong)電式沖擊扳手(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(ben)開(kai)關(guan)結(jie)構緊湊效(xiao)率(lv)高，大面積的固定式(shi)散熱片為(wei)開(kai)關(guan)的安裝提供方便。開(kai)關(guan)內部為(wei)單極常開(kai)帶直通接(jie)點結(jie)構，通過改變輸入(ru)脈沖(chong)的占空比(bi)來控制場效(xiao)應管(guan)的輸出(chu)電壓，而(er)實現電子調速功能。
◆開(kai)關輸出端的平(ping)均電(dian)壓(ya)為(wei)總電(dian)壓(ya)的8 - 50%至(zhi)8 - 90%，也(ye)可以(yi)按客戶要求進行(xing)定制，開(kai)關按到(dao)底由直通(tong)接點接至(zhi)電(dian)池端電(dian)壓(ya)。
◆可選帶以下功能或(huo)附(fu)件：
→外置(zhi)MOS管→智能調速功能，可帶軟啟動、欠壓保(bao)(bao)護、過流(liu)保(bao)(bao)護、電池過溫保(bao)(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(shu)入端/輸(shu)出端 Input side/Output side:
→焊接端子(zi) Solder terminal
