To match the GD350A IP20 series, INVT also offers the complementary GD350 variant with IP55 protection.

The GD350 IP55 is a powerful and versatile frequency inverter. The IP55 protection class offers a high level of protection even for demanding outdoor applications. The GD350 IP55 also features easy operation, excellent performance, high functionality for versatile applications. The frequency converter is equipped with an integrated main switch, enabling direct connection to the mains.

The GD350 is a dual-rated, high-performance frequency inverter series in the power range from 4 kW to 110 kW. The GD350 series integrates speed, torque and positioning control and includes features for IoT functionality. The frequency inverter has a two-channel STO function (SIL2) and a multi-line, multi-language LCD control panel. With a variety of option cards, the series is easily expandable.

The GD350 is widely used throughout mechanical and plant engineering, environmental engineering, and water/wastewater applications.

The GD350 series of frequency inverters takes advantage of fast response speeds of the latest processor technology to solve your drive task. As a result, it optimises the availability (IoT functionality), performance (precise torque control, perfect speed accuracy, extensive positioning functions) and user-friendliness (optional Wi-Fi and Bluetooth connection to mobile devices) of your application.

Thanks to its optional communication modules (Profinet®, EtherNet/IP®, EtherCAT®, ModbusTCP®, Ethernet® (UDP), GPRS (MQTT), Profibus/DP, CANopen) the GD350A meets the highest requirements of modern automation.

automation. Optional feedback cards are available for open-collector, HTL, TTL encoders as well as for resolver and sin/cos systems.

An optional integrated PLC card with 128kB program memory, 6 digital inputs, 2 relay outputs, 1 analogue input and 1 analogue output offers you further optimisation possibilities and can replace your external controller to realise your system cost-efficiently.

The GD350 series combines versatile options in one unit to operate different types of motors and meet different requirements.
