INVT GD350 series high performance vector inverters

The GD350 series, INVT's latest addition, includes High-performance vector invertersfor any type of electric motor and industrial application.
The result of more than 5 years of R&D work, the GD350 series is designed to meet any type of application requirement, even the most complex.
Innovative vector management algorithm with direct current control "I/F mode" (with or without sensor)the ability to control any type of motor (asynchronous or synchronous)and advanced torque control functions and the integrated positioner; allow the devices in this series to be used successfully in highly complex applications.

Infinite expansion possibilities

Built-in expansion slots allow you to increase the functionality of GD350 high performance vector inverters with communication extension boards (Ethernet, CANopen, Profibus, Profinet, EtherCAT, DeviceNet), feedback interfaces (incremental encoder, absolute encoder, resolver), I/O modules, integrated PLC board.
The Bluetooth module allows the inverter to be accessed and programmed by smartphone.
The integrated USB port allows simple and immediate connection to a PC for drive programming and monitoring.

Dedicated firmware for specific applications

Optionally, GD350 series inverters can be 'customised' with dedicated firmware for specific applications. See some examples:

GD350-16 Dedicated firmware for pumping systems

GD350-16 is a FW dedicated to pumping systems for different areas of use

• • Control of pumps with asynchronous or synchronous permanent magnet motors
  • Alternation control of up to 4 pumps
  • View setpoint e feedback in the actual unit of measurement
  • Dual PID controller and differential feedback from dual transducers
  • Function "pump cleaning”
  • Function sleep advanced
