DEW防塵（智能）直流扳機調速開關

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

產品描述Product description

◆DEW系列是一款通用型的直流扳機調速開關，集成防塵(chen)功能和機械剎車接點，不帶換向功能，一般應用(yong)于不需要換向的(de)直流(liu)電(dian)(dian)(dian)池式(shi)電(dian)(dian)(dian)動工具(ju)和園林工具(ju)，如：充(chong)(chong)電(dian)(dian)(dian)式(shi)電(dian)(dian)(dian)錘、充(chong)(chong)電(dian)(dian)(dian)式(shi)往(wang)復鋸、充(chong)(chong)電(dian)(dian)(dian)式(shi)曲(qu)線鋸、充(chong)(chong)電(dian)(dian)(dian)式(shi)角磨、充(chong)(chong)電(dian)(dian)(dian)式(shi)打草(cao)機、充(chong)(chong)電(dian)(dian)(dian)式(shi)吹吸機等(deng)。

◆DEW series are one general type DC variable speed trigger switches, integrated dustproof and mechanical brake contact, without reversing box, commonly for used in DC portable power-tools and gardening tools such as: Cordless Rotary Hammers, Cordless Reciprocating Saws, Cordless Jig Saws, Cordless Angle Grinders, Cordless Grass Trimmers, Cordless Blowers, etc.


產品特征Features

◆本開關(guan)結構緊(jin)湊(cou)效率高,大(da)面積的(de)固(gu)定式散熱片為開關(guan)的(de)安裝提供方(fang)便.開關(guan)內部為單極常開帶直(zhi)通(tong)接點結構,通(tong)過改變輸入(ru)脈(mo)沖的(de)占(zhan)空比來控制場(chang)效應管的(de)輸出(chu)電壓(ya),而實現電子(zi)調(diao)速功能.
◆開(kai)關輸出端的平均(jun)電壓為總電壓的8- 50%至8- 90%,也可以按(an)客(ke)戶要求進行定制,開(kai)關按(an)到底由直通接點(dian)接至電池端電壓.
◆可選帶以(yi)下(xia)功能或(huo)附件:
→外(wai)置MOS管
→帶軟(ruan)膠扳機
