Product Description:
The FC-301P4K0T4134L2953 is a variable-frequency drive produced by Danfoss for the VLT FC 301 Automation Drives series. Acting as a three-phase power conditioner, it supplies induction motors with user-defined voltage and frequency so that conveyors, pumps, and ventilation fans can follow precise speed commands. By modulating the fixed mains waveform, the unit connects plant power to motion loads, delivering adjustable torque, process repeatability, and energy savings in industrial automation.
Input compatibility spans 380–480 VAC, and the converter withstands a 3.0% phase imbalance without derating. At rated load, it outputs 4.0 kW at 400 V or the equivalent 5.0 hp at 460 V while holding terminal voltage at 100% of the supply voltage. Its frequency range reaches 590 Hz, with flux control limited to 300 Hz for enhanced low-speed torque. Command resolution is provided by a 12-bit analog channel; the analog input accepts up to 30 mA, digital inputs tolerate 28 V DC, and digital outputs can source 40 mA. The DC link should be charged no more than twice per minute. Pulse-width modulation maintains three-phase output integrity throughout these operating conditions.
High-speed position feedback enters through a pulse input rated for 110 kHz. Protective logic trips at 820 V DC to safeguard the semiconductors and connected machinery from excessive DC-bus voltage. When shielded motor leads are used, the maximum run length is 50 m; unshielded cable can extend to 75 m while still observing EMC limits. A displacement power factor of ≥0.9 minimizes reactive loading on the plant network. The drive also maintains the motor terminal voltage at the required level while adjusting output frequency for changing speed commands.
