Product Description:

The Danfoss FC-301P1K1T4134L2642 belongs to the VLT FC 301 Automation Drives series. It functions as an AC variable-frequency controller for three-phase motors. By converting fixed-frequency mains power into a modulated output, the drive lets an automation system match motor speed to real-time load requirements, improving energy use in pumps, fans, and conveyors across industrial facilities.

The input section accepts a line range of 380–480 VAC, so the drive can be installed on standard plant power without a transformer. Within this range, the inverter delivers a rated output of 1.1 kW, making it suitable for 1.5 horsepower motors. Electrical conversion efficiency reaches 0.96 at rated current, which limits heat generation and cabinet cooling demand. When starting a motor from zero speed, the control algorithm can produce up to 160% of rated torque, allowing loaded machines to overcome static friction without requiring an oversized drive. For high-speed applications, the unit supports output frequencies up to 590 Hz, permitting oversynchronous operation where process throughput depends on elevated impeller or spindle speed.

At 400 V, the apparent power drawn from the supply is 2.1 kVA, while the inverter can deliver a continuous 380–440 V output of 3.0 A to the motor terminals. Internal power dissipation under rated load is limited to 58 W, so thermal management can usually be handled with passive panel ventilation. Shielded motor leads may run up to 50 m while maintaining electromagnetic compatibility in noise-sensitive installations, and unshielded cables may support longer runs when installation conditions permit. Torque rise times are 1 ms in Flux mode and 10 ms in VVC+ mode, allowing the drive to respond quickly to changing load commands without exceeding its efficiency or thermal limits.
