SCF8C-E-U Quadro motori elettrici (

Controller per piccole pompe antincendio elettriche secondo EN 12845 e UNE 23500

I Controller SCF8C-E-U, sono piccoli strumenti facili da usare e configurabili, utili per azionare automaticamente le pompe da fuoco a motore elettrico, (Electric Fire Pumps) in qualsiasi ambiente

I controllori SCF8C-E-U avviano e arrestano automaticamente le piccole pompe antincendio elettriche (fino a 7,5kW) e/o le pompe Jockey (fino a 2,2 kW) a seconda della richiesta del sistema; le proteggono mediante gli allarmi collegati e generati dal controller, visualizzano i valori e le informazioni più rilevanti, gestire anche la comunicazione dell’operatore e sia gli elementi di contorno che il centro presidiato a distanza.
