A stand-alone frequency converter for fixed-speed pumps that are operated in variable applications, especially for heating, air conditioning and pressure boosting.

Special features/product advantages

• Compact design with an energy-saving cooling concept for lowering temperature losses
• Integrated energy-efficient harmonic reduction function in the pump’s partial load range
• Versatile pumping application scenarios thanks to differing connection options and different control modes
• Simple commissioning thanks to an intuitive assistant with graphical user interface

Options

• External communication via IF modules (optional): Profibus, DeviceNet, Profinet, Ethernet, Modbus
