INVT GD270-004-4 4kW High Performance Vector Control Variable Frequency Drive 380V VFD

INVT GD270-004-4 Vector Control Variable Frequency Drive

Product Overview

The INVT GD270-004-4 is a 4kW (5HP) high-performance vector control variable frequency drive from the GD270 series, engineered for precise motor speed and torque regulation in demanding industrial applications. Operating from three-phase 380V input, this advanced drive supports both open-loop sensorless vector control and closed-loop vector control with encoder feedback. With built-in braking chopper, Modbus RS485 communication as standard, comprehensive multi-function I/O, and full protection features, it is the ideal drive solution for pumps, fans, compressors, conveyors, mixers, and general industrial automation where high precision and reliability are essential.
