PEDROLLO MT 10 Steadypres Inverter with Water Passage

INSTALLATION AND USE

• STEADYPRES is an electronic device that manages and controls both surface and submersible pumps using inverter technology.
• STEADYPRES It is designed for water supply in homes, businesses, and irrigation purposes. Suitable for all kinds of pressurization systems, including existing ones, STEADYPRES enhances comfort, extends the system’s lifespan, and significantly reduces energy consumption.

PRODUCT DESCRIPTION

STEADYPRES is connected to the pump’s delivery system and regulates the motor’s rotation speed by adjusting the voltage and frequency of the output, in response to water flow demand, ensuring constant pressure within the system.
STEADYPRES components:

• electronic frequency converter (inverter);
• pressure and flow sensor;
• electrical panel with keypad and display to facilitate setting and reading operations;
• integrated and inspectable non-return valve.

STEADYPRES features include:

• A display and keypad for easy, step-by-step setup of operating parameters with two levels of adjustment:
  • BASIC, for setting pressure and current;
  • ADVANCED, for customizing the inverter for specific system needs .
• Internal electronic components are cooled as water flows through the device, helping to dissipate heat.

STEADYPRES protects the pump from:

• Dry running
• Overcurrents
• Overvoltage
• Undervoltage
• Overheating
• Short circuit
• Phase failure in connections (for TT version)

KEY FEATURES

• Easy installation, adjustment and setting.
• Energy saving due to lower absorption of the pump.
• Control of hydraulic and electrical operating parameters and protection against faults.
• Reduced noise operation.
• Longer pump life.

OPTIONAL A RICHIESTA

• Expansion board, which allows:
  • RS485 communication to link up to three STEADYPRES inverters and create pumping groups;
  • alternating pump operation;
  • configuration of a dry input contact (e.g. float, double set point);
  • configuration of a dry output contact (e.g. alarm)
