INVERTER FOR ELECTRIC PUMPS CONTROL
• It controls the starting and stopping of the electric pump and modulates the motor rotations according to the water request from
the system. Hammering is reduced and inrush starting current avoided.
• Constant pressure.
• 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.
• Automatic maximum frequency reduction with temperature.
• Programmable input and output for different functions (enable, double set-point, error, master/slave configuration).
• Multilingual display.
Optionals – special arrangements :
• I/O expansion card available.
• Cable for connection in twin booster sets 4x0.5 mm2 100 cm (SR-CBL4X05-100).
• Interface module SIRIO X4.
