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，集成防(fang)塵和機械剎車接點，內(nei)部帶換(huan)向結構，應(ying)用于(yu)各類直流(liu)充(chong)(chong)電(dian)(dian)式(shi)手(shou)(shou)持電(dian)(dian)動工具，如(ru)：充(chong)(chong)電(dian)(dian)式(shi)電(dian)(dian)鉆、充(chong)(chong)電(dian)(dian)式(shi)電(dian)(dian)錘、充(chong)(chong)電(dian)(dian)式(shi)螺絲起子、充(chong)(chong)電(dian)(dian)式(shi)沖擊(ji)扳(ban)手(shou)(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.


產品特征Features

◆本開(kai)關結構(gou)緊湊效率高，大(da)面(mian)積(ji)的(de)固定式散熱片為(wei)開(kai)關的(de)安(an)裝提供方便。開(kai)關內部(bu)為(wei)單(dan)極常(chang)開(kai)帶直通(tong)接點結構(gou)，通(tong)過改(gai)變輸入脈沖(chong)的(de)占(zhan)空比來控制場效應管的(de)輸出電壓，而實現電子調速功能(neng)。

◆開(kai)關輸(shu)出端(duan)的(de)(de)平均電壓為總電壓的(de)(de)8- 50%至8- 90%，也(ye)可以按(an)客戶要求進行定制，開(kai)關按(an)到底由直(zhi)通(tong)接點接至電池端(duan)電壓。

◆可選帶以下功能或附(fu)件:

→外置MOS管
→帶(dai)軟膠扳機
→外接LED及導線
→外接電池溫度(du)檢測(ce)導線

→智(zhi)能調(diao)速功能，可帶軟啟動、欠(qian)壓(ya)保(bao)護、過流保(bao)護、電池過溫(wen)保(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.
◆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
