◆DAK系列是一款通用型的直流扳機(jī)調(diào)速開關(guān)，集成防塵和機(jī)械剎車接點(diǎn)，內(nèi)部帶換向結(jié)構(gòu)，應(yīng)用于各類直流充電式手持電動(dòng)工具，如：充電式電鉆、充電式電錘、充電式螺絲起子、充電式?jīng)_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.
◆本開關(guān)結(jié)構(gòu)緊湊效率高，大面積的固定式散熱片為開關(guān)的安裝提供方便。開關(guān)內(nèi)部為單極常開帶直通接點(diǎn)結(jié)構(gòu)，通過(guò)改變輸入脈沖的占空比來(lái)控制場(chǎng)效應(yīng)管的輸出電壓，而實(shí)現(xiàn)電子調(diào)速功能。
◆開關(guān)輸出端的平均電壓為總電壓的8 - 50%至8 - 90%，也可以按客戶要求進(jìn)行定制，開關(guān)按到底由直通接點(diǎn)接至電池端電壓。
◆可選帶以下功能或附件:
→外置MOS管→智能調(diào)速功能，可帶軟啟動(dòng)、欠壓保護(hù)、過(guò)流保護(hù)、電池過(guò)溫保護(hù)
◆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
