AccessoriesInverter SIRIO UNIVERSAL
Inverter for electric pump control
- Choose the comfort of constant pressure and the silence of the pump that only an inverter system can offer.
- Universal model for electric pumps with single-phase 230V and tree-phase 230V motor output.
- Dry running protection, over pressure protection against leakages and against rotor blocking in one item only.
- It controls the start and stop functions of the traditional electric pump (surface, vertical and submersible) and modulates the motor rotations according to the water request from the system. Hammering is reduced and inrush starting current avoided.
- Constant pressure.
- Integrated pressure transducer.
- Possibility to desable the flow sensor if the water is not perfectly clean of ferrous.
- Energy saving
- Protection against dry running.
- Automatic reset in event of dry running
- Protection against leakages, over pressure, over heating, rotor blocking and abnormal power supply.
- Motor over current control
- Digital indication of the pressure, the voltage, the current and the motor frequency.
- Adjustment of the frequency with temperature´s increasing
- Programmable input and output for different functions( enable, double set-point, error, master/slave configuration)
- Multilinqual display with 16 characters
- Wi-fi connection from smartphone (optional)
