Inventer for single phase electric pump control
- Electronic device for the single phase electric pumps control based on inverter technology.
- It controls the start and stop 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 due to motor pump speed regulation.
- Energy saving due to less pump absorption.
- Programmable input and output for different functions (enable, double set-point, error, master/slave configuration).

- Gradual pump start and stop reduces hammering and avoids breakaway starting current.
- Protection against dry running in event of water shortage on the suction.
- Automatic reset in event of dry running, with autonomous error condition recovery.
- Efficient leakage monitoring to protect pump in event of repeated restarts.
- Digital indication of the pressure, the voltage, the current and the motor frequency.
- Motor over current control.
- Operation/error status signalling via LEDs and on-screen alerts.
- Operation in master/slave configuration into twin booster sets.
- Double set point with remote control option.
- Remote start and stop of electric pump.
