Wall-mounted driver with LCD display, for the control of two single-phase (MM) or three-phase pumps connected to 230 V (MT) managed by two frequency converters (INVERTER) inside the SPEEDBOX DUO. The electrical power supply of the appliance is single-phase 230 V (MM-MT). SPEEDBOX DUO mounts a double variator for the management of two electric pumps, which can therefore work in cascade or alternately, both under inverter. The 0-10 BAR pressure transducer is included (on request the transducer can be 0-16 BAR).
FUNCTIONAL CHARACTERISTICS
- Two frequency converters for the management of two electric pumps.
- 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.
PROTECTION SYSTEMS
- Control and protection system of the electric pump against overintensity
- Protection system against dry operation of the electric pump due to lack of water
- Abnormal supply voltage
- Short-circuit between system output phases
CONTROL PANEL
Control panel includes LCD screen, warning leds, push-buttons, START-STOP, AUTOMATIC and configuration system.
