DAK防塵（智能）直流扳機調(diào)速開關(guān)

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

產(chǎn)品描述Product description

◆DAK系列是一款通用型的直流扳機調(diào)速開關(guān)，集成防塵和機械剎車接點，內(nèi)部帶換向結(jié)構(gòu)，應用于各類直流充電式手持電動工具，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.


產(chǎn)品特征Features

◆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結(jié)構(gòu)，通過改變輸入脈沖的占空比來控制場效應管的輸出電壓，而實現(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行定制，開關(guān)按到底由直通接點接至電池端電壓。

◆可選帶以下功能或附件:

→外置MOS管
→帶軟膠扳機
→外接LED及導線
→外接電池溫度檢測導線

→智能調(diào)速功能,可帶軟啟動,欠壓保護,過流保護,電池過溫保護

◆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
