The INVT GD20-0R4G-S2 is a compact, universal inverter from the Goodrive20 series, designed for single-phase 220V AC input with a rated power of 0.4 kW. It enables efficient operation of three-phase asynchronous motors using standard single-phase power sources, making it an ideal solution for small-scale automation, commercial uses, and HVAC applications. With advanced sensorless vector control (SVC) in a miniaturized design, it is well-suited for conveyors, pumps, fans, and medical equipment.
Design Philosophy: Space Efficiency and Ease of Use
The GD20-0R4G-S2 emphasizes minimal space consumption and simplified integration. Its compact form factor and DIN rail mounting support allow easy installation in control cabinets alongside other automation components. This design makes variable frequency drive technology accessible for OEMs, small workshops, and retrofit projects where electrical and physical space is limited.
Key Features
Single-Phase to Three-Phase Operation: Converts 220V AC single-phase input to three-phase output, allowing the use of efficient three-phase motors in locations without three-phase power.
DIN Rail Mounting: Saves space and simplifies installation in control panels per EN 60715 standards.
Advanced Sensorless Vector Control: Provides 150% starting torque at 0.5 Hz and ±0.2% speed accuracy for high-performance motor control.
Integrated Connectivity: Features Modbus RTU over RS-485 for seamless integration into control systems, along with digital and analog I/O support.
Comprehensive Protection: Includes safeguards against overcurrent, overvoltage, undervoltage, overload, and short circuits.

Frequently Asked Questions
Why choose a single-phase input VFD like the GD20-0R4G-S2?
This drive allows the use of more efficient and reliable three-phase motors with only a single-phase power supply. It offers soft-start functionality to reduce mechanical stress, precise speed control for energy savings, and better overall motor performance.
What does the 'S2' suffix mean in the model name?
The 'S2' denotes a single-phase input version (220–240V AC), distinguishing it from models like the '-4' series, which are designed for three-phase input.
What installation factors ensure reliability for this small drive?
Ensure proper ventilation and clearance within the enclosure, correct cable sizing and grounding, and a operating environment free from excess humidity, dust, vibration, or high temperatures.
