LINETRAXX® VMD460-NA

Il VMD460 è un sistema di protezione d'interfaccia esterno che monitora tensioni e frequenze della rete e comanda l'apertura dei dispositivi di interfaccia e/o di rincalzo, qualora siano rilevati valori al di fuori dei limiti richiesti. Il VMD460 è un apparecchio multistandard, configurabile in base alle esigenze nazionali e dell'applicazione. I valori misurati vengono visualizzati continuativamente sul display LC, con memorizzazione dei valori che determinano l'intervento dei relè.
