1) GENERAL INFORMATION.

1) GENERAL INFORMATION. 1) GENERAL INFORMATION. 1) GENERAL INFORMATION.
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.
WARNING: Correct compliance with the installation and operating instructions and the electrical
connection diagrams will guarantee the correct operation of the unit.
DANGER: The failure to follow the instructions in this Manual can lead to motor overloads,
diminishment in technical characteristics, reduction of the unit's working life and all types of
subsequent results, for which we decline any responsibility.
