INVT GD20-022G-4 High-Power Industrial Drive Reliable General-Purpose VFD

The INVT GD20-022G-4 is a 22kW high-power general-purpose frequency inverter from INVT's GD20 series, engineered for heavy-duty industrial drive applications requiring robust performance and high output capacity. Designed for three-phase 380V power input, this powerful drive delivers stable V/F and sensorless vector control for large induction motors up to 22kW. With built-in DC reactor for harmonic suppression, integrated braking chopper, PID control, Modbus RTU communication, independent air duct cooling, and comprehensive protection functions, it is the cost-effective drive solution for large pumps, industrial fans, air compressors, extruders, heavy conveyors, crushers, mixers, and demanding industrial automation where reliable high-power motor control is required.

• High-Power Industrial Drive — 22kW G-type rating with 150% overload for 60s and 180% for 3s; built-in DC reactor reduces input harmonics and improves power factor for continuous heavy-duty operation
• Reliable General-Purpose VFD — Proven GD20 platform scaled to 22kW with V/F and sensorless vector control (SVC), delivering stable speed regulation, reliable output, and essential automation features at a competitive cost
• Heavy-Duty Motor Controller — SVC mode provides 150% starting torque at 0.5Hz with 1:100 speed control range and ±0.5% speed accuracy, suitable for heavy-starting loads in crushers, extruders, and large mixers
• Built-in DC Reactor — Integrated DC reactor as standard, reducing input current harmonics by up to 30%, improving input power factor to above 0.9, and protecting the drive from mains voltage transients
• Advanced Process Control — Integrated PID controller with sleep/wake function for closed-loop pressure, flow, and temperature regulation; multi-speed and simple PLC for standalone automation sequences
• Robust Thermal Design — Independent air duct cooling isolates power electronics from control circuitry; high-capacity DC fans and coated PCBA ensure reliable operation in dusty and humid factory environments
• Comprehensive Protection Suite — Overcurrent, overvoltage, undervoltage, overload, overheating, input/output phase loss, short-circuit, PTC motor protection, and automatic fault recording with alarm relay output
• Simple System Integration — RS485 Modbus RTU standard, intuitive keypad with parameter copy function, motor auto-tuning, and application presets for quick commissioning across pumps, fans, and conveyors
