INVT GD350-2R2G-4 Multi-Function Vector Inverter Heavy-Duty Motor Drive

The INVT GD350-2R2G-4 is a 2.2kW multi-function vector inverter from INVT's flagship GD350 series, delivering heavy-duty (G-type) performance with smart control intelligence for small to mid-size industrial drive applications. Built on an open-platform architecture with integrated PLC functionality, the GD350-2R2G-4 provides high starting torque, precise speed regulation, and robust overload capacity in a compact footprint. Supporting a wide range of motor types and communication protocols, it is the versatile drive solution for small machine tools, winding/unwinding systems, packaging, conveyors, textile machinery, mixers, compressors, and general industrial automation where intelligent programmable control and reliable performance are required.

• Multi-Function Vector Inverter — 2.2kW G-type rating with 150% overload for 60s and 180% for 3s; supports V/F, open-loop vector (SVC), closed-loop vector (FVC), PMSM sensorless, and torque control modes for demanding applications
• Heavy-Duty Motor Drive — 150% starting torque at 0.5Hz (SVC) and 180% at 0Hz (FVC); 1:100 speed range (SVC), 1:1000 (FVC); designed for constant torque applications requiring high breakaway torque
