DUM系列開(kāi)關(guān)電源系統(tǒng)是為電信、無(wú)線基站等通訊設(shè)備設(shè)計(jì)的高頻開(kāi)關(guān)電源系統(tǒng)。產(chǎn)品采用高頻軟開(kāi)關(guān)技術(shù)，

N+1模塊組合結(jié)構(gòu)，模塊間自動(dòng)均流。整機(jī)體積小，重量輕，工作溫度范圍寬，抗干擾能力強(qiáng)，電網(wǎng)適應(yīng)能力強(qiáng)，動(dòng)態(tài)響應(yīng)快，雜音紋波小，開(kāi)關(guān)頻率高。系統(tǒng)配有遠(yuǎn)端通信接口，可進(jìn)行遠(yuǎn)程通信及管理。機(jī)箱采用型材結(jié)構(gòu)、造型美觀，并有多種規(guī)格供用戶選擇。

DUM series switch power supply system is designed for telecom, RBS,and like these communicationequipments. The product uses the soft-switching technique, N+1 modules which are automatic currentsharing. It is small in size,light,wide temperature range,strong antijamming ability,suit wire netting well,fastdynamic response,low ripple,high frequency. Having long distance communication port for communicationand manage. Cabinet having graceful shapement,and not only one spec for user.
