Danfoss Inverter VLT Refrigeration Drive FC 103

Save energy and extend the lifetime of refrigeration applications
The VLT® Refrigeration Drive FC 103 is designed to help significantly reduce the lifecycle costs of your refrigeration systems. It offers efficiency- and reliability-enhancing features, integrated process control functions and a commissioning environment specially designed to meet the needs of refrigeration applications. It also features a setup Wizard which uses common refrigeration terms. This makes installation and commissioning easy and safe for refrigeration technicians and installers.

The continuous variable speed control provided by the VLT Refrigeration Drive makes intelligent capacity control possible. By creating stability while balancing the capacity to the actual load, system-wide coefficient of performance improves providing significant energy savings in a wide range of applications.

The drive contains all modules necessary for compliance with EMC standards. The integrated, scalable RFI filter minimizes electromagnetic interference, and the integral DC link chokes reduce harmonic distortion in the mains network. As these features are built in to the drive in the factory, cabinet space can be reduced. Efficient EMC mitigation also enables the use of cables with small cross sections which reduces installation costs.

Supply voltages and power range

• 3 x 200-240 V...1.1-45 kW
• 3 x 380-480 V...1.1-560 kW
• 3 x 525-600 V...1.1-7.5 kW
• 3 x 525-690 V...75-800 kW

• Reduce energy consumption and maintenance requirements thanks to a range of pump features such as the pump cascade controller and flow compensation
• Optimize system efficiency by taking advantage of the drive’s software features
• Run reliably in challenging environments due to the specially coated electronics
• Say goodbye to external cooling or oversizing, since the drive operates efficiently up to an ambient temperature of 50°C without derating
• Always stay EMC compliant thanks to integrated DC link harmonic and EMC filters
• The integrated, scalable RFI filter minimizes electromagnetic interference, and the integral DC link chokes reduce harmonic distortion in the mains network. Since these features are integrated, you save cabinet space.
• Efficient EMC mitigation also enables the use of cables with small cross sections which reduces installation costs.
