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
→帶軟膠扳機(jī)
→外接LED及導(dǎo)線
→外接電池溫度檢測(cè)導(dǎo)線
→智能調(diào)速功能,可帶軟啟動(dòng),欠壓保護(hù),過(guò)流保護(hù),電池過(guò)溫保護(hù)
◆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.
