Analitzador de xarxes MCA Plus II<\/h2>\n
L’analitzador de xarxes MCA Plus II<\/strong> \u00e9s un instrument electr\u00f2nic que permet la lectura dels principals par\u00e0metres avan\u00e7ats de la xarxa d’alimentaci\u00f3 en veritable valor efica\u00e7.<\/span><\/p>\n Est\u00e0 especialment dissenyat per a la seva f\u00e0cil instal\u00b7laci\u00f3 i programaci\u00f3, precisa la connexi\u00f3 de quatre terminals de tensi\u00f3 i tres transformadors de corrent. El teclat t\u00e0ctil capacitiu frontal permet canviar el par\u00e0metre visualitzat en pocs segons.
