GENERAL REMARKS
STEADYPRES is a speed controller with the following features:
- Powered by AC single-phase or three-phase
- Output AC single-phase or 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)
- It works in stand-alone configuration or in parallel with other units, through serial connection.
- 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.
- Adapts to any type of system pressurization, even existing
- Limits the peak currents during starts and operation, energy-saving.
- Allows the selection of the power supply and output voltage.

- In applications in parallel, there is a MASTER inverter that controls one or two SLAVE inverter.
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 goes back to being self-employed and will continue to operate
independently
When working in parallel with other inverters, STEADYPRES controls the alternation of starting to
make the use of the pumps uniform.
