Product Description:
The FC-301P30KT2131B8977 is an AC variable-frequency drive produced by Danfoss within the VLT FC 301 Automation Drives series. It converts fixed-frequency plant power into a regulated waveform so induction motors can be started, stopped, and speed-controlled through a closed-loop PLC in material-handling, pumping, and general process equipment. Continuous output is rated at 30 kW, which corresponds to a mechanical output of 40 HP. These ratings establish the thermal and electrical sizing requirements for connected motors.
The input range of 200–240 VAC supports low-voltage industrial grids, and the converter is designed for a three-phase power supply commonly used in industrial facilities. Motor output frequency can be adjusted through 0–590 Hz, while the output voltage tracks 0–100% of the supply voltage to support motor torque throughout the operating range. A flux-mode range of 0–300 Hz allows vector algorithms to maintain magnetizing current during overspeed operation. The unit tolerates a 3% mains imbalance and maintains a true power factor of at least 0.9 to limit reactive power draw. Four standard digital inputs, expandable to five, accept 0–24 V DC signals for start, stop, and preset commands, and the same voltage level applies to logic outputs. Motor leads may extend up to 50 m in shielded conduit or 75 m when unshielded without exceeding the drive’s carrier-frequency limits.
Line synchronization is maintained across a supply frequency of 50/60 Hz with a ±5% tolerance, and the displacement power factor remains above 0.98 to support efficient plant operation. An isolated process output provides a configurable 0/4–20 mA signal for monitoring pressure, speed, or torque. The form-C relay can switch up to 240 V AC at 2 A, allowing direct interlocking with contactors or fault indicator lights. The series identifier is 301, and the drive belongs to the VLT AutomationDrive FC product group.
