GENERAL REMARKS
DGBOX is a range of ELECTRONIC CONTROL PANELS for single pumps or pumping units.
DGBOX is powered by three-phase 400 Va.c. (optional version 230 Va.c.) and drives motor pumps with
three-phase 400 Va.c. (or 230 Va.c.) motors.
•
It maintains the system at constant pressure
at a level defined by the linked unit and adapts pump
or pumping unit performance to the instantaneous requirement. A second operating pressure can
also be defined, which can be enabled by means of an external signal.
• It carries out
continuous controls on electric and functioning parameters
, saving the pumping unit
from all common failures (over-currents, dry running, etc)
• It works in
stand-alone configuration or in parallel with other units,
through serial connection.
• in parallel configuration with other units, DGBOX makes the alternation in starting the pumps.
