Product Description:

The FC-301PK55T4134L2911 is a compact AC variable frequency drive produced by Danfoss for the VLT FC 301 Automation Drives series. The unit converts fixed-frequency industrial mains power into a regulated output that allows control systems to command induction motor speed and torque. Used in conveyors, pumps, and general machinery, it provides closed-loop motor control to reduce energy use and improve process consistency. Its compact frame fits standard control cabinets without requiring changes to existing panel layouts.

Designed for a three-phase power supply, the drive accepts line voltages from 380 to 480 VAC and delivers up to 0.55 kW of mechanical power to the motor terminals. Its output current capacity is 1.8 A across that voltage range, supporting applications with moderate load demands. At 400 V, the apparent power draw is 1.3 kVA, and the internal conversion efficiency reaches 0.95, so the drive produces only 42 W of heat at rated load. A starting torque equal to 160% of the motor’s nominal torque provides breakaway force against static friction. Flux control achieves a torque rise time of 1 ms, while VVC+ modulation achieves a response time of 10 ms. The power factor remains at or above 0.9, and the drive has a Category III overvoltage rating for installation on industrial distribution panels.

Continuous operation at full current is allowed at an ambient temperature of up to 45 °C and at altitudes of up to 1000 m without derating. The inverter tolerates a supply phase imbalance of 3.0% while maintaining stable motor control. Shielded motor cables may be up to 50 m long, while unshielded motor cables may be up to 75 m long. These cable limits help contain electromagnetic emissions and maintain accurate current regulation. Power-loss management keeps generated heat within the enclosure’s cooling capacity, which supports reliable operation under the stated temperature, altitude, and wiring conditions.
