Product Description:

The FC-301P45KT4131B6463 is an AC variable frequency drive produced by Danfoss as a member of the VLT FC 301 Automation Drives series. It converts fixed-frequency, three-phase mains power into a modulated output so plant controllers can adjust induction motor speed and torque without mechanical throttling. In automated lines, the unit acts as the central power stage that optimizes energy use, regulates process flow, and provides electronic protection for connected motors.

The drive delivers a continuous output of 45 kW, equivalent to 60 hp, giving it the capacity to run medium-sized pumps, fans, and conveyors. It accepts a supply range of 380–480 VAC from three-phase power and tolerates voltage swings of ±10% plus line frequency variations of up to ±5%, so it remains stable on typical industrial feeders. A displacement power factor above 0.98 limits reactive current, while the true power factor remains at or above 0.9 to reduce total input current demand. Its Category III overvoltage design allows connection inside building distribution panels. Phase imbalance must not exceed 3.0% to avoid overcurrent trips. The drive permits a maximum of one power-up per minute.

Control interfaces include a 0–10 V analog output with 12-bit resolution for real-time speed feedback to external controllers. Two programmable digital outputs can each source up to 40 mA at frequencies as high as 32 kHz, enabling fast status signaling or pulse-train forwarding. Motor leads may be routed through up to 50 m of shielded cable or 75 m of unshielded cable without exceeding the stated electromagnetic compatibility limits, which provides flexibility when positioning the drive cabinet. When shielded cable is used, the shield must be bonded at both ends to maintain drive-side radio-frequency interference compliance.
