Product Description:

The FC-301P22KT2134L2709 is a variable frequency drive produced by Danfoss and assigned to the VLT FC 301 Automation Drives series. As a power converter, it modulates the voltage and frequency delivered to an AC induction motor, enabling precise speed and torque regulation in conveyors, pumps, fans, and other automated plant equipment. By replacing mechanical throttling with electronic control, the unit supports energy-efficient operation across a wide operating range.

The drive connects to three-phase supplies within a range of 200–240 VAC, tolerating line variation of ±10% without derating. It draws a continuous line current of 80 A and can furnish a steady motor current of 88 A; these values guide upstream fuse sizing and conductor selection. A power rating of 22 kW indicates the maximum continuous shaft load the inverter can sustain, while the built-in overload reserve of 150% for 60 seconds lets machines overcome breakaway friction or momentary process spikes. Phase imbalance on the supply is limited to 3.0% to keep rectifier stress uniform. The control board provides 12-bit analog feedback to external controllers for speed or torque monitoring. Shielded motor leads may extend up to 50 m, while unshielded runs may extend up to 75 m before additional filters are required.

Pulse-width modulation up to 32 kHz reduces audible switching noise and lowers motor iron losses at low speed. Conversion efficiency reaches 0.97, keeping thermal dissipation at the rated load loss of 874 W, which standard cabinet fans can remove. An input displacement power factor exceeding 0.98 and a true power factor of at least 0.9 limit reactive current, so feeder conductors remain close to their active-power amperage. During regenerative deceleration, the inverter limits the overload output current to 132 A.
