Product Description:

The FC-301P3K7T2134G0684 is an AC variable frequency drive manufactured by Danfoss as part of the VLT FC 301 Automation Drives series. The unit converts fixed-frequency, three-phase mains power into an output with adjustable voltage and frequency. This conversion gives industrial control systems precise speed regulation for centrifugal pumps, fans, conveyor motors, and other compatible equipment.

Operation begins with a three-phase input rated at 200 - 240 VAC and a maximum line current of 15 A. Phase imbalance must remain below 3.0% to reduce the risk of overcurrent trips. The inverter delivers a continuous motor current of 16.7 A, corresponding to a mechanical output of 5.0 HP, or 3.7 kW. Output frequency is adjustable from zero to 590 Hz, while magnetic flux can be tracked up to 300 Hz for vector control. At rated load, the drive reaches an efficiency of 0.96, limiting the portion of input energy dissipated as heat. The control section provides a 12-bit analog output for process feedback and accepts pulse references up to 110 kHz. No more than two power-ups per minute are permitted to protect the DC-link capacitors. Shielded motor cables may extend up to 50 m, while unshielded cables may extend up to 75 m without exceeding the supported cable lengths.

The estimated power loss is 185 W, which should be considered when providing enclosure ventilation and heat-sink airflow. The drive supports three-phase motor outputs across the same voltage range used by the input supply. Its logic terminals handle 24 V class signals, and each digital input tolerates levels up to 28 V DC. The transistorized digital output can source up to 40 mA for compatible status relays or indicator lamps. Adequate ambient cooling helps keep the heat sink within its permitted operating limits during continuous service. Appropriate cable shielding also helps control radiated electrical noise when the drive and motor are installed in industrial machinery.
