为什么电子负载不能串联使用

如今跟(gen)着电(dian)(dian)(dian)子(zi)产(chan)品电(dian)(dian)(dian)压(ya)的(de)不断攀(pan)升,400V,600V甚(shen)至1000V,能知足(zu)如斯高电(dian)(dian)(dian)压(ya)的(de)电(dian)(dian)(dian)子(zi)负(fu)载型号(hao)非常有限(xian)。于是良多(duo)人(ren)就(jiu)会考虑将多(duo)台电(dian)(dian)(dian)子(zi)负(fu)载串联的(de)办法(fa),但是绝大部门的(de)电(dian)(dian)(dian)子(zi)负(fu)载都(dou)是无法(fa)串联使(shi)用的(de)。电(dian)(dian)(dian)子(zi)负(fu)载

    欧洲promax的使用方法

    欧洲(zhou)promax的(de)使用方法:①正(zheng)确(que)连接(jie)电缆(lan),连接(jie)电缆(lan)不宜(yi)过(guo)长。假(jia)若(ruo)非用长电缆(lan)不可(ke)时,则必须在仪表的(de)读数上(shang)加上(shang)电缆(lan)的(de)损耗,尤其是高频(pin)段。②欧洲(zhou)promax不仅要测量图像载波电平,还要测量调频(pin)声音广播(bo)信号

    FLUKE红外热像仪正确使用的注意事项有哪些呢?

    FLUKE红(hong)(hong)外(wai)热像(xiang)仪(yi)应用原(yuan)理就是(shi)将物体(ti)发出的不可见红(hong)(hong)外(wai)能量转(zhuan)变为可见的热图像(xiang),并(bing)通过红(hong)(hong)外(wai)发射器测(ce)量目标温度(du)最终呈现(xian)在显示屏上(shang)。这种简(jian)单、快速、精(jing)准又安全(quan)的探测(ce)仪(yi)器的诞生,无疑是(shi)众多检测(ce)维(wei)护(hu)行业的福音,

    高德手机式热像仪的原理、优点和选择要点

    高德手(shou)(shou)机式热像仪是红(hong)外(wai)(wai)传感器(qi)的诸多应用(yong)中非常重要(yao)的一种应用(yong),从最初仅限(xian)于作为高科技产品,现在已经越来(lai)越普遍(bian)地走向工业和(he)民(min)用(yong)市场。高德手(shou)(shou)机式热像仪是利用(yong)红(hong)外(wai)(wai)探测器(qi)和(he)光学(xue)成像物镜接受(shou)被(bei)测目标的红(hong)外(wai)(wai)辐射能量(liang)

    目前测量蓄电池内阻的常见方法有哪些呢?

    内(nei)阻(zu)(zu)又称内(nei)电(dian)(dian)(dian)阻(zu)(zu)。电(dian)(dian)(dian)池(chi)的内(nei)阻(zu)(zu)是指电(dian)(dian)(dian)池(chi)在(zai)工(gong)作时,电(dian)(dian)(dian)流流过电(dian)(dian)(dian)池(chi)内(nei)部所受到的阻(zu)(zu)力。一般分为交流内(nei)阻(zu)(zu)和(he)直(zhi)流内(nei)阻(zu)(zu)。由(you)(you)于充电(dian)(dian)(dian)电(dian)(dian)(dian)池(chi)内(nei)阻(zu)(zu)很小,测(ce)直(zhi)流内(nei)阻(zu)(zu)时由(you)(you)于电(dian)(dian)(dian)极容(rong)量极化,产生极化内(nei)阻(zu)(zu),故无(wu)法测(ce)出(chu)其(qi)真实值,而测(ce)其(qi)交流内(nei)

    什么是直流电源?有哪些特点呢?

    直(zhi)流电(dian)(dian)(dian)(dian)(dian)源是不是觉得(de)不太熟悉(xi),告(gao)诉(su)你,我们常见的(de)干电(dian)(dian)(dian)(dian)(dian)池(chi)、蓄电(dian)(dian)(dian)(dian)(dian)池(chi)都是直(zhi)流电(dian)(dian)(dian)(dian)(dian)源,这(zhei)下知道(dao)了吧,直(zhi)流电(dian)(dian)(dian)(dian)(dian)源是维持电(dian)(dian)(dian)(dian)(dian)路中形成恒电(dian)(dian)(dian)(dian)(dian)压电(dian)(dian)(dian)(dian)(dian)流的(de)装(zhuang)置。直(zhi)流电(dian)(dian)(dian)(dian)(dian)源有正、负两个电(dian)(dian)(dian)(dian)(dian)极(ji),正极(ji)的(de)电(dian)(dian)(dian)(dian)(dian)位高,负极(ji)的(de)电(dian)(dian)(dian)(dian)(dian)位低,当两个电(dian)(dian)(dian)(dian)(dian)极(ji)与电(dian)(dian)(dian)(dian)(dian)路
