SPEEDBOX DUO SET Three-phase/three-phase wall inverter for the control of two electric pumps

Wall-mounted driver with LCD display, for the control of two three-phase 400 V pumps managed by a frequency converter (INVERTER) and a power relay. The appliance is powered three-phase at 400 V. SPEEDBOX DUO SET manages two-pump pressurization units via an electronic system and software that allow the exchange and alternation of the two electric pumps; one managed by an inverter and the other by a power relay. Therefore, the pump managed by the inverter will be changed at each operating cycle. The 0-10 BAR pressure transducer is included (on request the transducer can be 0-16 BAR). The SPEEDBOX has an air cooling system and an optional EMC filter for residential class.

• Two frequency converters for managing the main electric pump.
• Power relay for managing the auxiliary pump.
• Alternating sequence of operation.
• ART function (Automatic Reset Test): when the pump is deactivated by the dry-running protection system, ART makes, with programmed intervals, attempts to start the pump to restore the pressure in the circuit every 30 minutes for 24 hours.
• Automatic reset system after accidental interruption of the power supply. The system starts up maintaining the configuration parameters.
• Potential free switched contact to monitor alarms originating from system irregularities or problems with display indication. Use with single-phase input.
• Minimum level control via external float.
• STC (Smart Temperature Control) function: when the board temperature exceeds 85° C, the rotation frequency of the electric pump automatically decreases, decreasing the temperature but maintaining the supply of water.
• Control panel with multifunction LCD display, LED indication and buttons
• Current intensity sensor with digital instant readout.
• Pressure transducer 0-10 bar (0-16 bar on request) with 4-20 mA input.
• Operations log. Possibility of displaying: working hours, number of starts, number of connections to the electricity grid
• Alarm log. Display of the number and type of alarm generated by the device.
• Possibility of intervention on the PID.
• Aluminum heat exchanger and natural or forced convection heat dissipation.
