Product Description:
The FC-301P22KT4131H3986 is a variable frequency drive produced by Danfoss and supplied within the VLT FC 301 Automation Drives series. Designed for cabinet mounting in industrial plants, the unit converts fixed-frequency three-phase mains into a controlled AC output that allows connected systems to regulate motor speed and process throughput. By replacing mechanical throttling with electronic regulation, it supports smoother acceleration and more consistent operation in conveyors, pumps, and other general-purpose production equipment.
The drive delivers a continuous mechanical output of 30 HP, which is equivalent to 22 kW. Its input bridge accepts line voltages from 380-480 VAC, allowing direct connection to common industrial power systems without additional voltage conversion equipment. Because the converter is designed for three-phase power, the incoming load remains balanced across the supply conductors during normal operation. A current-controlled IGBT section generates the variable-frequency output, and an integrated EMC filter helps reduce conducted interference on the mains and motor cables. Analog references, digital I/O, and serial communication options allow the drive to respond to speed commands and process signals within automated control systems.
The internal identifier 301 places the unit in the FC 301 platform, where the control structure supports flexible motor regulation for industrial duty. Control functions include vector-based motor control, which helps the drive maintain stable speed behavior when the load changes during operation. A built-in PID regulator allows the drive to manage process variables such as pressure, flow, or conveyor response without requiring a separate external control loop. Protective routines monitor phase loss, output short circuits, and heat sink temperature, while the fault history buffer stores recent events for diagnostics. Cooling air is drawn through the base plate, allowing side-by-side mounting in dense cabinets when the surrounding temperature remains within the recommended operating range.
