Product Description:
Danfoss supplies the FC-301P1K1T4131B0934 variable frequency drive as a member of the VLT FC 301 Automation Drives series. The unit is listed under the VLT AutomationDrive FC product group and carries the internal series identifier 301. It is built to adjust the speed of three-phase induction motors in conveyors, pumps, and general material-handling machinery, delivering closed-loop control while occupying minimal cabinet space. The converter processes fixed mains power into a variable-voltage and variable-frequency output suitable for an installed motor rated at 1.1 kW.
Designed for industrial grids, the drive accepts a 380–480 VAC three-phase supply and draws a maximum input current of 2.7 A. Apparent input power reaches 2.1 kVA, and conduction and switching losses are limited by an efficiency of 0.96 at rated current. The output section supports a motor output of 1.5 HP and supplies 3.0 A continuously at 380–440 V or 2.7 A in the 441–500 V range; intermittent demand of up to 4.8 A is permitted during acceleration. Overvoltage supervision issues a DC-link warning at 810 V DC and activates braking at 728 V DC to protect the internal bus. Installation rules permit no more than two power-ups per minute, helping preserve rectifier and capacitor life. These electrical limits support operation on common three-phase industrial power systems while accommodating short acceleration loads.
The inverter generates a carrier-controlled output of up to 590 Hz, while an internal flux mode maintains vector regulation up to 300 Hz for applications that require constant torque at elevated speeds. At rated load, the drive dissipates only 58 W of heat, which aids enclosure cooling calculations. DC-link protection trips at 820 V DC, isolating the bus before semiconductor limits are exceeded. Supply quality must remain within a 3.0% phase imbalance to keep current distortion within operating limits. The available output frequency begins at zero hertz, allowing precise speed matching across a wide range of compatible motor types.
