Product Description:

The FC-301P3K7T2131X7265 is an AC variable frequency drive manufactured by Danfoss for the VLT FC 301 Automation Drives series. Installed in control cabinets, the unit modulates three-phase power to regulate motor speed and torque in industrial conveyors, centrifugal pumps, and general process equipment. By converting a fixed mains frequency into a variable output frequency, it supports precise automation while reducing mechanical stress on driven machinery.

The drive delivers a continuous apparent power of 6.65 kVA at 230 V, indicating the combined reactive and real load that the converter can handle without overheating. On the line side, the drive draws a continuous current of 15 A, while its inverter can supply 16.7 A to the motor windings. The input section accepts a 200–240 VAC three-phase supply, eliminating the need for a step-down transformer in low-voltage plants. At rated current, the power stage reaches an efficiency of 0.96, meeting the IE2 energy-efficiency class and lowering heat dissipation inside the control cabinet. The digital inputs accept signals up to 28 V DC, supporting connections to common industrial control devices. The transistor output supplies 40 mA and switches at 32 kHz, allowing it to support high-speed encoder simulation.

The drive has a motor output rating of 5.0 HP, which corresponds to 3.7 kW. It can produce a starting torque of up to 160% for 60 seconds to overcome static friction during startup. Flux control provides a torque rise time of 1 ms, enabling tight speed regulation during rapid load changes. Installation without derating is permitted at altitudes up to 1,000 m, while operation at altitudes up to 3,000 m is possible with appropriate derating. Motor cables may extend up to 50 m when shielded or 75 m when unshielded before output filtering limits are exceeded. The three-phase topology supports balanced wiring and compatibility with suitable three-phase protective devices.
