KDW127/12B矿用(yong)浇封兼本安(an)型直(zhi)流稳压电(dian)源(yuan)

KZC18矿用(yong)本安型(xing)信(xin)号转(zhuan)换器(qi)(qi)(以下(xia)简(jian)称信(xin)号转(zhuan)换器(qi)(qi))是煤矿网(wang)络通讯监控系统的终(zhong)端配套(tao)产品，属于(yu)矿用(yong)本质安全型(xing)设(she)备。它将(jiang)VDSL信(xin)号和TCP/IP网(wang)络信(xin)号进(jin)行(xing)双向转(zhuan)换，从(cong)而提高了现(xian)(xian)有设(she)备的利用(yong)率，节约了投资，还可在既(ji)有的网(wang)络基础(chu)上简(jian)化布线复杂(za)度;轻松地将(jiang)现(xian)(xian)有的VDSL设(she)备连接到局域(yu)网(wang)或Internet。
