現(xiàn)在大多數(shù)工程師在測(cè)試LED電源時(shí),有的用LED燈珠,有的用普通型的電子負(fù)載,有用1000多元,有用3000元的,但市面上大多的電子負(fù)載是不能模擬LED燈珠的,所以,測(cè)試出來的功率因數(shù)應(yīng)該是不正確的.這也是為什么CHROMA,以及博計(jì)推出專用的LED電子負(fù)載. 同時(shí),深圳新能基科技也推出了相應(yīng)的電子負(fù)載,具有LED,CC,CP,CV,CR等五種模式,不但可以測(cè)試LED電源,也可以測(cè)試充電器,適配器等電源,是一個(gè)多功能的電子負(fù)載.具有與CHROMA,博計(jì)一樣的功能,但價(jià)格相對(duì)應(yīng)來說要低很多.
預(yù)計(jì)年底可以量產(chǎn),敬請(qǐng)大家的期待! (同時(shí),新能基將參加 電源網(wǎng)11月電源技術(shù)論壇,屆時(shí)請(qǐng)大家參觀指導(dǎo)!)
但,具有測(cè)試LED功能的電源測(cè)試系統(tǒng),新能基科技早電子負(fù)載一步推了出來,一經(jīng)推出得到廣大電源企來的青睞.
真正實(shí)現(xiàn)LED電源測(cè)試的自動(dòng)化, 為電源企業(yè)提高生產(chǎn)效率,降低測(cè)試成本.
