Vector control frequency inverter GeoDrive

with analog interfacethree-phasesingle-phase

Product summary
GeoDrive GD20 and GD350 are frequency inverters developed for precise, energy-efficient control of electric motors in industrial ventilation and extraction applications. GD20 provides basic sensorless vector control for smaller motors, while GD350 delivers extended control and safety functions for larger installations. Both models are designed for integration with Geovent ventilation components and control systems.

What do you get?

• Precise motor speed and pressure regulation adapted to ventilation systems.
• Energy-saving operation through adjustable motor control.
• Reduced acoustic emission thanks to controlled motor speeds.
• Simplified installation and commissioning for fast system integration.
• Long-term operational reliability with model-specific enclosure protection.
• Compatibility with Geovent fans, MultiBox IV and PowerSmart control systems.
• GD20 covers basic needs; GD350 adds advanced control and safety options.

Product information
GD20 is suited for applications requiring compact, cost-effective motor regulation and uses sensorless vector control technology. It includes an EMC filter class C2. GD350 targets higher-power and safety-critical ventilation installations, provides additional control functions and safety features, and is supplied with an EMC filter class C3 to reduce electromagnetic interference. Installation of a 300 mA residual current device (RCD) is required to meet electrical safety standards.
