Product Description:

The FC-302P1K5T5E is an AC variable frequency drive produced by Danfoss within the VLT FC 302 Automation Drives series. Belonging to the VLT AutomationDrive FC product group, this controller converts fixed three-phase mains power into a regulated output that allows plant PLCs to adjust induction motor speed and torque. By matching motor flux to the load, the unit improves energy use and reduces mechanical wear in conveyors, pumps, and material-handling cells commonly found in industrial automation lines.

It accepts a three-phase input of 380–500 VAC and carries the internal series identifier 302. With supply voltages between 380 and 440 V, it delivers a continuous output current of 4.1 A, while the rating decreases to 3.4 A when the supply reaches 500 V. The inverter produces up to 2.0 HP, or 1.5 kW, of mechanical output power with an efficiency of 0.97 at rated current. Output frequency can be adjusted from zero to 590 Hz, and the dedicated flux-mode range reaches 300 Hz for field-oriented control. A true power factor of at least 0.9 indicates that reactive current is minimized, supporting utility compliance and allowing the use of smaller upstream fuses. The three-phase power architecture and VLT control core maintain steady torque during rapid speed adjustments.

For demanding starts, the inverter supplies a starting torque of 160% for 60 seconds and can sustain a 110% overload for 0.5 seconds to clear brief jams. Torque rises quickly because flux-vector mode reaches full response in 1 ms, while the VVC+ algorithm requires 10 ms. Protective functions monitor the DC link; braking activates at 810 V DC, a high-voltage warning appears at 840 V DC, and an overvoltage alarm triggers at 855 V DC. At steady load, the heat sink dissipates only 62 W, supporting compact cabinet layouts. The displacement power factor remains above 0.98, reducing reactive current demand and electrical stress on the supply system.
