This inverter drive is a highly efficient solution designed for continuous control of three-phase AC motors. The inverter drive operates at a power rating of 3kW and features a supply voltage of 400V AC. Its compact design allows for installation in various industrial settings, while the IP20 rating ensures adequate protection in controlled environments.

• Utilises Modbus communication for seamless integration
• Equipped with Safe Torque Off (STO) for enhanced safety
• Compact dimensions facilitate installation in confined spaces
• High power density optimises system performance
• Includes built-in filters to reduce harmonic distortion

• Ideal for speed control of conveyor systems
• Suitable for operation in pumps and fans
• Can be integrated into mixers and compressors
• Utilised in basic handling machines

The Safe Torque Off (STO) feature ensures that the inverter drive stops the motor safely, minimising the risk of unintentional movement during maintenance or faults, compliant with IEC 61508 SIL 2 standards.

The device allows a maximum output frequency of 550Hz, accommodating higher operational speeds for various industrial applications.

Yes, it supports Modbus communication, enabling efficient data transfer and integration with existing control systems.

Being an IP20 inverter drive, it is suitable for installation in dry indoor conditions, typically found within control cabinets or close to machinery in industrial settings.

The compact design allows for ease of installation in tight spaces and helps optimise overall control cabinet sizes, advantageous for system integrators and machine builders.
