Product Description:

The FC-301P3K7T2134L2901 is a variable frequency drive built by Danfoss within the VLT FC 301 Automation Drives series. The unit modulates the voltage and frequency supplied to an induction motor, letting machine builders regulate shaft speed and torque without mechanical throttling. In automated conveyors, mixers, or pump skids, this drive replaces constant-speed starters and allows real-time process adjustment through integrated control terminals. It occupies minimal panel depth and shares parameter menus with other FC 301 variants, simplifying setup.

It connects to industrial mains in the 200 to 240 VAC range and is intended for three-phase power grids. At that supply, the inverter delivers a rated shaft power of 3.7 kW, which corresponds to approximately 5.0 HP. It provides a continuous motor current of 16.7 A while drawing no more than 15 A from the line. Electrical efficiency reaches 0.96 at rated current, so only 4% of the input becomes heat. Two digital pulse outputs and one relay output provide status and fault signals to host controllers. Apparent power at 230 V is 6.65 kVA, keeping feeder sizing moderate, while the true power factor remains at or above 0.9 to reduce reactive load. The permissible phase imbalance is 3.0%, which helps protect the input rectifier.

For dynamic applications, the inverter can raise the synthesized frequency to 590 Hz, while a separate flux-mode ceiling of 300 Hz supports extended speed ranges on lightly loaded motors. Internal cooling limits semiconductor dissipation to 185 W at rated load, enabling continuous operation in ambient temperatures up to 45 °C. Installation is permitted at altitudes up to 1000 m without derating. Above that altitude, current scaling is required to keep the drive within its operating limits. The available frequency range supports high-speed motor operation when the connected motor and load are suitable. Integrated cooling helps control internal temperatures without requiring a separate liquid-cooling circuit.
