Product Description:

The FC-301P15KT2134L2973 is an AC variable-frequency drive manufactured by Danfoss and supplied under the VLT FC 301 Automation Drives series. The unit converts fixed-frequency, three-phase power into a modulated output for controlling induction motors. Automation controllers can use the drive to regulate motor speed and torque in conveyors, pumps, and general process equipment while reducing unnecessary energy consumption.

The drive connects to a three-phase plant supply of 200 to 240 VAC and draws 68 A of input current at nominal load. Its electrical section provides a continuous output current of 74.8 A and delivers up to 15 kW to the motor terminals. Conversion efficiency reaches 0.96, so a relatively small portion of the incoming power is dissipated as heat. Normal operation permits 110% loading for one minute every ten minutes, while brief demand can raise the current to 82.3 A without causing a protective shutdown. The inverter accepts a maximum phase imbalance of 3.0% to protect its rectifier bridge. Power-up frequency is limited to one start per minute to reduce stress on the internal capacitors. At maximum load, the drive produces 737 W of thermal loss that must be removed through adequate cabinet ventilation.

A 24 V DC control terminal rated for 200 mA can supply external sensors and other compatible control devices. A 12-bit analog output provides scaled feedback signals to a supervisory PLC, while the AC relay contact supports pilot duties at 240 V and 2 A. The permitted shielded motor cable length is 50 m, allowing the drive to be installed at a practical distance from the connected motor. An unshielded motor cable may extend up to 75 m when the installation does not require cable shielding. These cable limits help control electrical interference and switching effects across the motor connection. The control terminals, analog output, and relay contact support integration with common industrial automation systems without requiring separate signal-conversion equipment.
