The STEADYPRES 4.0 by Pedrollo is an inverter for single-phase and three-phase 230 Volt surface and submersible electric pumps.
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.
STEADYPRESS 4.0 is used for domestic water supply and irrigation; it adapts to any type of pressurization system, even existing ones, ensuring maximum comfort, increasing the average life of the system and allowing significant energy savings.
It ensures the durability of the system, because 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.
