GD20 frequency inverter
The GD20-EU is a compact frequency inverter series ranging from 0.4 kW to 110 kW in various frame sizes. The GD20-EU series offers excellent sensorless vector-control performance across the entire speed range.
The frequency inverter has a certified STO function (SIL2/SIL3), carries CE marking and UL/cUL certification for ratings up to 11 kW, and is approved by TÜV SÜD. The GD20-EU is widely used in global machinery and plant engineering, the paper and plastics industries, and water/wastewater applications.
The GD20-EU series meets the requirements of a wide range of speed-control applications and enables energy-efficient operation of pumps and fans.
In addition, the GD20-EU supports your application through programmable sequence control. The GD20-EU series combines versatile capabilities in one device to drive different motor types and meet a broad range of application requirements.
