1.1) Description

1.1) Description
1.1) Description 1.1) Description
The Speedrive inverters have been designed to adjust the speed of three
The inverter receives a signal from the pressure transducer that is proportional to the installation's pressure. This
signal is processed and it regulates the speed of the motor to keep the pressure constant, even though the
consumption of water varies.
It can be used with 50Hz or 60Hz motors. Selecting the output frequency with the menu option.
The units have a constant pressure control system. The PI system used provides two numerical constants that are
processed by the unit to achieve a stable regulation.
This type of regulation can greatly reduce the consumption of energy when compared to unregulated systems,
since the consumption of electricity will be proportional to the consumption of water. Another of the advantages
of regulated units is the decrease in voltage surges, softening current peaks and, therefore, increasing the
working life of the pump.

1.3) Dry run protection

1.3) 1.3) 1.3) Dry run protection Dry run protection. . . . Dry run protection
If the unit detects that a pump is not receiving intake water, it will stop and the "DRY RUN" alarm will be activated,
with 3 reset attempts until the unit completely shuts down in order to repair the problem or breakdown in the
intake of this pump.
