OPERATION AND SYSTEM REQUIREMENTS
.
DGFIT is a speed controller
with the following features:
-
Powered by AC single-phase or three-phase
-
Output AC three-phase
-
It maintains the system at
constant pressure
(VARIABLE SPEED CURVES)
-
It carries out
continuous controls
on electric and functioning parameters, saving the
pumping unit from all common failures (over-currents, dry running, etc)
-
Adapts to any type of system
pressurization, even existing
-
Limits the peak currents during starts and operation,
energy-saving
.
-
applications in parallel, with a MASTER inverter and SLAVE inverters, controlled by the
MASTER.
-
The MASTER receives the programming of the parameters and controls the operating data,
and activates and deactivates the SLAVE as needed.
If the MASTER is turned off, the SLAVE becomes independent and will continue to operate
independently.
WORKING LIMITS
-
fire / explosion:
inverters DGFIT
ARE NOT SUITABLE
for operation in environments
with risk of explosion.
-
Maximum ambient temperature:
40 °c; DGFIT cannot be mounted in a limited and
sealed environment (no air exchange), eg. an underground box, for cooling reasons.
-
Supply voltage tolerance
: + / - 10% compared to the nameplate data
-
Enclosure IP54:
DGFIT is protected against access of dust and water to the
electronics, but the environment levels of dust or dirt must not limit or impair, over the
time, the smooth operation of the cooling fans of inverter.
