Product Description:
The FC-301P1K5T4131B0953 is a three-phase AC variable frequency drive produced by Danfoss within the VLT FC 301 Automation Drives series. As an AutomationDrive unit, it regulates induction motor speed and torque for conveyors, pumps, and material-handling equipment used in industrial automation. By modulating output frequency and voltage according to process demand, the drive can reduce mechanical wear and energy consumption in distributed machine cells. Its variable-speed operation allows connected machinery to run at the level required by the application rather than continuously operating at full speed.
The inverter’s power section is rated at 1.5 kW when connected to a three-phase supply between 380 and 480 VAC. At 400 V, it can supply a continuous apparent power of 2.8 kVA while maintaining an efficiency of 0.97, so approximately 3% of the supplied energy is lost as heat. The motor terminals carry up to 4.1 A during steady operation, and the input bridge draws a maximum of 3.7 A from the line under rated load. These current levels allow the drive to operate with small IEC frame motors without requiring unnecessarily large upstream fuses or cables. Its three-phase topology provides balanced loading and supports smooth torque production across the available speed range.
The control layer accepts 0–10 V or 4–20 mA reference signals and withstands up to 28 V DC on its logic inputs. Two programmable digital outputs can source or sink signals, and each channel supports currents up to 40 mA. Pulse rates can reach 32 kHz, allowing the outputs to provide high-resolution status feedback. The analog feedback output can drive loads with an impedance as low as 500 Ω, permitting a direct connection to compatible panel meters. At rated load, the inverter dissipates 62 W, which keeps cabinet ventilation requirements modest. Shielded motor cables can extend up to 50 m, while unshielded cables can extend up to 75 m without exceeding the stated electromagnetic compatibility limits.
