INVT’s GD20-EU series of open-loop vector control frequency inverters

INVT introduces the GD20-EU family of high-performance variable frequency drives with advanced capabilities for reliable drive control through vector control technology.

The series features improved reliability and wider usability than its predecessors and market counterparts, enabling complex and optimized hardware configurations with advanced functionality for a wide range of applications in modern industrial automation:

• Frequency inverter models from the 18.5 to 110 kW power range come standard with a built-in DC reactor;
• The models up to 37 kW – with a built-in standard brake module;
• From 45 to 110 kW – with optional built-in brake module.
• Built-in STO function for the entire power range
• Built-in input filter for powers over 4kW

The advantages in a nutshell

Key benefits of the GD20-EU family of frequency converters are increased reliability, efficiency and performance and an innovative design optimized to meet the requirements of diverse systems and applications in modern industry.

Excellent driving performance:

• Vector control mode without the need for an engine speed sensor;
• Excellent motor drive efficiency;
