Product Description:
The FC-301P15KT4134L2921 is a variable frequency drive manufactured by Danfoss for the VLT FC 301 Automation Drives series. In automated plants, it modulates the voltage and frequency supplied to three-phase AC motors, enabling controllers to match motor speed and torque to changing load conditions instead of running at a fixed line frequency. The unit mounts inside control cabinets, where it communicates with PLCs and field networks to govern conveyors, pumps, fans, and other material-handling equipment.
It draws power from a three-phase supply rated at 380–480 VAC and converts that energy into a motor output of up to 15 kW, which is equivalent to 20 HP. Within this range, the inverter can deliver output frequencies as high as 590 Hz, supporting high-speed spindles or blowers. For difficult starts, the drive supplies 160% of rated torque for 60 seconds every 10 minutes, helping heavy loads reach operating speed without requiring an oversized motor. It carries an IE2 energy-efficiency classification, maintains a true power factor of at least 0.9, and supplies full current when the ambient temperature remains at or below 45 °C. A power-up rate limited to once per minute protects the internal DC-link capacitors from thermal stress.
Control inputs tolerate levels up to 28 V DC, allowing standard sensors to issue run or fault commands without level shifting. Torque builds quickly; in flux control, the rise time is 1 ms, while VVC+ mode reaches steady torque in 10 ms. Flux-mode operation is limited to 300 Hz, and the maximum output voltage is equal to 100% of the incoming supply voltage. Shielded motor leads may extend to 50 m, while unshielded leads may extend to 75 m before dv/dt limits are exceeded. A displacement power factor of greater than 0.98 minimizes reactive current and supports favorable utility power quality.
