The STEADYPRES 4.0 by Pedrollo is an inverter for single-phase and three-phase 230 Volt surface and submersible electric pumps.
This inverter works with both single-phase power supply and single-phase motor output and with single-phase power supply and three-phase motor output but at 230 volts.
It is applied to the delivery of the electric pump and, by modulating the value and frequency of the output voltage, allows the rotation speed of the motor to be varied according to the quantity of water required, thus ensuring constant pressure in the system.
The STEADYPRESS 4.0 is suitable for domestic water supply and irrigation; it adapts to any type of pressurization system, even existing ones, ensuring maximum comfort, increasing the system's average lifespan, and allowing for significant energy savings.
It helps ensure the durability of the system, as it protects against dry running, overcurrent, undervoltage, overtemperature, short circuit or current leakage.
The Pedrollo inverter is very simple and intuitive to use thanks to a well-organized control panel and LED indicators that show the operating status of the instrument.
