PRODUCT DESCRIPTION
VSP is a speed regulator with the following characteristics.
• It receives mono-phase or three-phase alternating voltage.
• It supplies alternating three-phase output voltage.
• Check motor on 3 phases.
• Variable speed adjustment (inverter)
• Keeps system pressure constant (curves with variable rotations).
• Checks hydraulic and electrical operating parameters and protects the electric pump from faults.
• It is 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.
• It limits the peak and operating currents, with energy saving.
• It allows selection of the supply and output voltage.
• Maximum current electronic control for overload (adjustable)
• Protection against over or under voltages
• Electronic control for dry run (cos φ adjustable)
• Automatic reset from dry run with cycle times separately programmable from 0÷120 minutes
• Alarm output (NC-C-NO resistive load - 5A / 250V)
