EW800 Il meter distribuito multifunzione

Il meter distribuito EW800 costituisce un sistema accurato in grado di monitorare in maniera puntuale l’utilizzo dell’energia e la qualità della linea di un carico trifase. Permette all’utente di raccogliere in maniera distribuita tutti i consumi rilevanti di energia e i parametri elettrici di un impianto elettrico o di una linea di macchinari, incluso il contenuto armonico fino alla 51ma.

I dati di ogni singolo EW800 vengono quindi inviati a un data manager o tramite RS485 o via Radio 868MHz.
Una rete di meter connessa ad un singolo data manager può contare fino a 250 dispositivi
Un utente da remote può raccogliere I dati dal Data Manager utilizzando un web server embedded in un formato compatibile HTML5.

Caratteristiche:

  • Contatore di energia trifase/monofase
  • Misura dell’energia attiva, reattiva e apparente
  • Misura della potenza attiva, reattiva e apparente.
  • Misura dei parametri elettrici: corrente, tensione, potenza attiva, reattiva , apparente, fattore di potenza.
  • Misure di qualità della rete: armoniche (1st…51th), THD.
  • Possibilità di creare una rete fino a 250 contatori che interagiscono attraverso un Data Manager serie EW900.
  • Precisione: Class 1 per energia attiva
  • Comunicazione (opzioni) : ModBus RS485, Radio Sub1Ghz (868MHz)

Interfaccia utente:

  • Display grafico 256×96 pixel, retroilluminato a LED bianchi
  • Menu intuitive con interfaccia touch screen resistivo
  • Rinfresco dati : 1 ssecondo

ESA Automation offre 3 tipi di meter:

  • EW800A3A (DEM) Misurazione diretta fino a 64 ARMS
  • EW800B3A (DTM) Misurazione tramite TA
  • EW800C3A (DRM) Misurazione tramite Rogowski Coils
