PRODUCT DESCRIPTION
• STEADYPRES is an electronic command and control device for a surface or submerged pump, based on the inverter tech-
nology.
• It is applied to the delivery of the electric pump and, by adjusting the frequency of the current, allows you to vary the
rotation speed of the motor based on the quantity of water required, guaranteeing constant pressure on the system.
• The pressure is easily adjusted by the user using two keys and  is placed on the control panel with a value between
1 and 9 bar.
• A versatile product which, with a unique device, can combine with a SINGLE-PHASE or THREE-PHASE electric pump thanks
to a selector inside which allows selection of the output phases.
• Cooling of the electronic internal components is guaranteed by the water which crosses the device and allows its heat
dissipation.
• It protects the electric pump from dry running, overcurrent, short circuit or current dispersion and low voltage power
supply.
• It can be equipped with an expansion board, which allows working parallel with other inverters in the pumping unit and
management of an input and an output signal.
• It adapts to every type of pressurisation system, even existing.
USE BENEFITS
• Easy installation, adjustment and setting.
• Energy savings thanks to less absorption of the electric pump.
• Checks hydraulic and electrical operating parameters and protects the electric pump from faults.
• Higher operating silence.
• Reduced water consumption.
• Longer duration of the electric pump over time.
