GK920 18.5KW 380V 3PH GB - VSD/VFD
GK920 18.5KW 380V 3PH GB - VSD/VFD
The GTAKE GK920-4T18.5GB is a 18.5kW three-phase 380–440V AC variable speed drive (VSD/VFD) with built-in braking unit from the GK920 Series High Performance AC Motor Drives range, rated for 37A output current. It delivers precise V/f, sensor-less vector and closed-loop vector control for pumps, fans, compressors, conveyors and general industrial machinery, giving accurate speed regulation, smooth starting and lower energy consumption.
The GK920 supports flexible frequency setting via keypad, analog inputs, pulse input or Modbus communication, with multi-step speed, simple PLC and process PID functions built in. It suits new installations and like-for-like replacements for OEMs, panel builders, mines, water utilities and maintenance teams.
Key Features
- V/F and vector motor control with configurable command and feedback options.
- PID, multi-step speed and drive logic functions.
- RS-485 communication and optional fieldbus expansion.
- Book-type construction for space-efficient control panels.
- Motor and drive protection functions; braking arrangements vary by model suffix.
