產(chǎn)品描述Product description

◆DJK系列是一款專(zhuān)用型的直流扳機(jī)調(diào)速開(kāi)關(guān)，集成防塵和機(jī)械剎車(chē)接點(diǎn)，內(nèi)部帶換向結(jié)構(gòu)，應(yīng)用于各類(lèi)直流電池式手持電動(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。
◆DJK series are one special type DC variable speed trigger switches, integrated dust-proof, 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.

產(chǎn)品特征Features

◆本開(kāi)關(guān)結(jié)構(gòu)緊湊效率高，大面積的固定式散熱片為開(kāi)關(guān)的安裝提供方便。開(kāi)關(guān)內(nèi)部為單極常開(kāi)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(kāi)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(hù)要求進(jìn)行定制，開(kāi)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
→外接發(fā)光LED及導(dǎo)線(xiàn)
◆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 various dimensions.
◆Average duty cycle of motor voltage 8 - 50% to 8 - 90%, then by-pass to battery voltage (according to customer's demand).
◆Optional with the function or accessory as follows:
→Extrenal MOSFET version
→Auxiliary LED and wires
