The NCT355 series includes various sizes of inverters with specific programs for the handling of cranes and bridge cranes which differ from each other in the maximum output current that can be supplied and the possibility of operating with 380/400VAC or 230VAC mains voltage , three-phase or single-phase.

The main features of the inverters of this series are:

1. Essentiality of all the functions specifically designed with a view to lifting equipment and construction cranes.
2. Simplification of the electrical panel as the commands can arrive directly from the manipulator or from the 48VAC push-button panel without the need for auxiliary relays.
3. Calibrations reduced to the bare minimum that can also be performed by non highly
4. qualified personnel with the help of a simple screwdriver and a digital tester.
5. Diagnostics on LCD display to facilitate identification of any causes of alarm.
6. Automatic limitation of the output current and protection against short circuits.
7. Operation guaranteed with ambient temperatures between -10 °C and +60°C.
8. Very wide tolerance on supply voltage and automatic speed reduction in case of
9. exceptionally low supply voltage.
10. Specific programs for rotation, trolley, lifting, translation, etc.
11. Three-speed operation for all movements.
12. Implementation of the “traditional assembly” and “hydraulic assembly” functions in the
13. lifting.
14. Implementation in the lifting of the “brake contactor safety” function.
15. Possibility of directly managing an anemometer, an encoder, a load cell, a potentiometer.
16. Possibility of implementing the “limit switch” and “limit switch deceleration” management.
17. Possibility of memorizing and maintaining speeds even on intermediate points.
18. Possibility to set the speed with a potentiometer.
19. “Stop brake” function on rotation.
20. Language change function.
21. Recording of alarms and working times to facilitate diagnostics.
22. RS232 serial port for remote assistance.
