Description
Danfoss Inverter-VFD MircoDrive Series
The Danfoss VLT® Micro Drive FC 051 is a compact, general-purpose Variable Frequency Drive (VFD) designed for motor control in simple to moderate industrial applications. It is renowned for its reliability, ease of commissioning, and cost-effectiveness
Key Features and Specifications
- Automatic Energy Optimization (AEO): This feature automatically adjusts the voltage output to the motor, minimizing energy consumption by maintaining the optimal magnetizing current for the current load
- Automatic Motor Tuning (AMT): Ensures an optimal match between the drive and the connected AC motor, improving control stability and motor performance
- Process PI-Controller: The drive has a built-in Process PI-Controller, which often eliminates the need for an external PLC for simple closed-loop control applications (like maintaining a constant pressure or flow)
- Built-in RFI Filter: Minimizes electromagnetic interference (radio frequency interference) from motor cables, simplifying installation and compliance
Typical Applications
- Pumps and Fans (where the AEO feature provides significant energy savings)
- Conveyors and Material Handling Equipment
- Textile Machinery
- Mixers and Agitators
- Small HVAC (Heating, Ventilation, and Air Conditioning) Systems
