TH1775直流(liu)偏置電流(liu)源

簡要介紹(shao)     

TH1775型直(zhi)(zhi)(zhi)流(liu)(liu)(liu)(liu)偏(pian)置電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)源（也稱直(zhi)(zhi)(zhi)流(liu)(liu)(liu)(liu)磁(ci)化電(dian)(dian)(dian)(dian)源）主要用(yong)于電(dian)(dian)(dian)(dian)感(gan),變壓器線圈進行(xing)(xing)電(dian)(dian)(dian)(dian)感(gan)測(ce)量(liang)時(shi)施加直(zhi)(zhi)(zhi)流(liu)(liu)(liu)(liu)偏(pian)置電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)，對(dui)該類儀(yi)器除需(xu)達到(dao)所需(xu)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)外，還需(xu)有對(dui)電(dian)(dian)(dian)(dian)感(gan)量(liang)測(ce)量(liang)影(ying)響(xiang)小(xiao)，頻(pin)(pin)(pin)率響(xiang)應(ying)寬（疊(die)加直(zhi)(zhi)(zhi)流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)時(shi)可使用(yong)高頻(pin)(pin)(pin)LCR表進行(xing)(xing)測(ce)量(liang)）等要求(qiu)。該產(chan)品通過微處理(li)器控(kong)制，采(cai)用(yong)自(zi)動電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)平衡原理(li)進行(xing)(xing)交直(zhi)(zhi)(zhi)流(liu)(liu)(liu)(liu)疊(die)加及電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)的(de)(de)穩定，可正向或反向輸出(chu)0－20A(TH1775)范(fan)圍(wei)的(de)(de)恒定電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu),特(te)別是TH1775適用(yong)頻(pin)(pin)(pin)率響(xiang)應(ying)達到(dao)1MHz。該產(chan)品產(chan)生的(de)(de)附加誤差小(xiao)，頻(pin)(pin)(pin)響(xiang)得(de)到(dao)大幅提(ti)升，大大拓(tuo)寬了(le)磁(ci)芯電(dian)(dian)(dian)(dian)感(gan)器的(de)(de)偏(pian)流(liu)(liu)(liu)(liu)測(ce)試中(zhong)的(de)(de)應(ying)用(yong)范(fan)圍(wei)。直(zhi)(zhi)(zhi)接(jie)受控(kong)于TH2816A/TH2817A/TH2818/TH2819及多點電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)掃描輸出(chu)功(gong)能為(wei)方(fang)便(bian)地進行(xing)(xing)磁(ci)性材料分(fen)析提(ti)供了(le)良好的(de)(de)解決方(fang)案。
