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(yīng)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(jìn)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:
→外置二極管
→帶軟膠扳機(jī)
→外接LED及導(dǎo)線
→外接電池溫度檢測導(dǎo)線
