INGEDRIVE LV 400 Frequency converters

air or water-cooled, low-voltage

The LV400 series of the INGEDRIVE™ converter range is composed of low-voltage frequency
converters. They are designed to control induction, synchronous or permanent magnet motors in a
wide range of industrial and marine applications. Its modular design makes it possible to encompass
a wide range of powers and voltages while its intuitive structure facilitates its use and maintenance.
The whole Ingedrive converter range offers a powerful configuration tool enabling the user to view
and parameterise drives both locally using the touch screen and remotely via an Ethernet connection.
