The NCT357 inverter is an ultra-compact inverter of small size and low cost but with very high performance, specifically designed for applications on cranes and bridge cranes, but which can also be used for many other applications.
The range of motors that can be operated with this inverter goes from a minimum of 0.2-0.3 Hp to a maximum of 5-5.5 Hp, provided that the conditions of use are not very stressful. The main features of the NCT357 inverter are:
Essentiality of all the functions specifically designed with a view to lifting equipment and construction cranes.
Simplification of the electrical panel as the commands can arrive directly from the manipulator or from the 48 Vac push-button panel without the need for additional relays.
Calibrations reduced to the bare minimum that can also be performed by non highly qualified personnel using the appropriate on-board four-button keypad.
Display of active commands and alarm diagnostics on 16 x 2 character alphanumeric display Automatic limitation of the output current and protection against short circuits.
Guaranteed operation with ambient temperatures between -10° C and + 50° C.
