DAK防塵（智能）直流扳機調速開關

DAK series Dustproof (Multi-function) DC Variable Speed Trigger Switches

產品描述Product description

◆DAK系列是一款通用型的直流扳機調速開關，集(ji)成(cheng)防塵(chen)和機械剎車接點(dian)，內部帶換向結構，應(ying)用于各(ge)類直流充(chong)(chong)電(dian)(dian)(dian)式(shi)(shi)手持電(dian)(dian)(dian)動工具(ju)，如(ru)：充(chong)(chong)電(dian)(dian)(dian)式(shi)(shi)電(dian)(dian)(dian)鉆、充(chong)(chong)電(dian)(dian)(dian)式(shi)(shi)電(dian)(dian)(dian)錘、充(chong)(chong)電(dian)(dian)(dian)式(shi)(shi)螺絲起子、充(chong)(chong)電(dian)(dian)(dian)式(shi)(shi)沖擊扳手等。

◆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.


產品特征Features

◆本開關(guan)結構(gou)緊(jin)湊效(xiao)率高，大(da)面(mian)積(ji)的(de)固定式散熱(re)片為(wei)開關(guan)的(de)安裝提供方便。開關(guan)內部為(wei)單極常開帶直通接(jie)點結構(gou)，通過改(gai)變輸入脈沖的(de)占空比來(lai)控制場效(xiao)應管的(de)輸出電壓，而實現電子調速(su)功能。 

◆開關(guan)輸出(chu)端的平均電(dian)(dian)壓為(wei)總(zong)電(dian)(dian)壓的8- 50%至(zhi)8- 90%，也(ye)可以(yi)按客(ke)戶要求進(jin)行(xing)定制，開關(guan)按到底由直通接(jie)點(dian)接(jie)至(zhi)電(dian)(dian)池端電(dian)(dian)壓。

◆可選帶以(yi)下功能或(huo)附件:

→外(wai)置MOS管(guan)
→帶軟膠扳機
→外接LED及導線
→外接電池溫度檢測(ce)導線

→智(zhi)能調(diao)速功能,可(ke)帶軟(ruan)啟動(dong),欠(qian)壓保護,過流保護,電(dian)池(chi)過溫保護

◆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.
◆Average duty cycle of motor voltage 8 - 50% to 8 - 99%, then by-pass to battery voltage (according to customer's demand).
◆Optional with the function or accessories as follows:
→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
