◆DAK系列是一款通用型的直流扳機調速開關，集成防塵和機械剎車接點，內部帶換向結構(gou)，應用于各類(lei)直流充(chong)電(dian)(dian)式手持電(dian)(dian)動工具，如：充(chong)電(dian)(dian)式電(dian)(dian)鉆(zhan)、充(chong)電(dian)(dian)式電(dian)(dian)錘、充(chong)電(dian)(dian)式螺絲起(qi)子、充(chong)電(dian)(dian)式沖擊扳(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.
◆本開關(guan)結構緊湊效率高，大(da)面積的固定式散熱片為(wei)開關(guan)的安裝提供方便(bian)。開關(guan)內部為(wei)單極常開帶直通接點結構，通過改變輸(shu)入脈沖的占空比來控制場效應(ying)管的輸(shu)出電(dian)壓，而實(shi)現電(dian)子調速功能。
◆開關(guan)輸出端的平均電(dian)(dian)壓(ya)(ya)為(wei)總電(dian)(dian)壓(ya)(ya)的8 - 50%至8 - 90%，也可以按(an)(an)客戶(hu)要求進行(xing)定(ding)制(zhi)，開關(guan)按(an)(an)到底由直(zhi)通(tong)接點接至電(dian)(dian)池端電(dian)(dian)壓(ya)(ya)。
◆可選帶以下功能或(huo)附件:
→外置(zhi)MOS管→智能調速功能，可帶軟啟(qi)動、欠壓(ya)保護(hu)、過流保護(hu)、電(dian)池(chi)過溫保護(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
◆輸入端/輸出端 Input side/Output side:
→焊接端子 Solder terminal
