GK920 280KW 380V 3PH G - VSD/ VFD

The GTAKE GK920-4T280G is a high-power 280kW (380HP) three-phase 400V AC variable speed drive (VSD/VFD) from the GK920 Series High Performance AC Motor Drives range. Built for reliable industrial motor control, this GK920 inverter delivers precise V/f, sensor-less vector and closed-loop vector control for heavy industrial loads such as large compressors, mills, extruders, mine winders and water/wastewater pumping stations. With a rated output current of 520A and an output frequency range of 0.00–600.00Hz, the GK920-4T280G is engineered for accurate speed regulation, strong overload capacity (150% for 1 minute, 180% for 10 seconds, 200% for 0.5 seconds) and dependable performance in demanding industrial environments across South Africa.

Housed in a compact IP20 book-type wall-mounted enclosure (Frame S09), the GK920-4T280G is forced-air cooled and suited to installation in control panels and switchrooms. It supports flexible frequency setting via digital keypad, terminal UP/DOWN, analog inputs (AI1–AI4), pulse input or Modbus/optional communication cards, along with multi-step speed, simple PLC, process PID and flexible motor start/stop and braking functions — making it a versatile drop-in replacement or new installation drive for OEMs, panel builders and industrial end users.
