Product Description:
The FC-301P37KT2134L2636 is a variable frequency drive produced by Danfoss for the VLT FC 301 Automation Drives series. As a three-phase inverter, it accepts an input range of 200–240 VAC and modulates that supply to run standard induction motors in automated conveyors, pumps, and material-handling stations. The unit converts constant line power into a programmable output waveform, enabling controlled motor speed regulation without mechanical throttling. Its compact design supports installation in automated systems that require adjustable speed, controlled acceleration, and consistent motor operation.
The power section can deliver up to 50 HP, corresponding to a continuous electrical rating of 37 kW, while maintaining the output voltage at 100 percent of the incoming supply voltage. Frequency adjustment ranges from zero to a maximum fundamental frequency of 590 Hz, while a separate flux-optimization channel reaches 300 Hz to minimize core losses during low-speed operation. The pulse-width modulation stage can switch at 32 kHz, and the drive tolerates a mains phase imbalance of 3.0 percent without derating. Internal measurements provide a minimum true power factor of 0.9, supporting efficient use of the feed transformer. The system permits one power-up per minute so that the DC link has sufficient time to discharge before the unit is energized again.
The programmable analog output has 12-bit resolution and can drive loads with resistance as low as 500 Ω for real-time process feedback. Logic terminals accept control signals up to 28 V DC, and each transistor output can supply 40 mA to annunciators or interlocks. High-speed pulse references are processed at rates up to 110 kHz, supporting responsive follower performance in positioning tasks. Shielded motor cable runs may extend up to 50 m, while unshielded conductors may extend up to 75 m without exceeding the stated electromagnetic compatibility limits. These cable allowances provide flexibility when routing motor connections through equipment frames, control cabinets, and production areas. Proper separation of power and control wiring helps preserve signal quality when the drive operates near switching equipment or other sources of electrical interference.
