Product Description:

The FC-301P30KT2134L2710 is an AC variable frequency drive produced by Danfoss for the VLT FC 301 Automation Drives series. In plant environments, it modulates three-phase mains power to regulate induction motor speed. This operation lets controllers match torque to process demand while limiting energy use in pumps, conveyors, spindles, and other motor-driven equipment.

The drive connects to a three-phase supply between 200 – 240 VAC and delivers up to 30 kW of continuous output power. During normal duty, the inverter supplies a rated line current of 115 A, while overall conversion losses remain low because of an efficiency of 0.97. Motor frequency can be adjusted from zero up to 590 Hz, supporting constant-torque loads as well as high-speed pump or spindle applications. Input current at nominal load reaches 104 A, and the control board provides a 12-bit analog output for proportional feedback to external instruments. Digital counters can drive the pulse input at up to 110 kHz, enabling precise flow or position adjustment through high-resolution encoder signals. The product belongs to the VLT AutomationDrive FC group and carries the internal series identifier 301.

The unit corresponds to 40 HP when expressed in imperial units and can sustain 150% loading for 1 minute during each 10-minute interval. Dynamic braking engages when the DC bus reaches 390 V DC, and an alarm is raised if the voltage increases to 410 V DC. Flux optimization is available at frequencies up to 300 Hz, allowing the controller to regulate motor magnetization across a broad operating range. Shielded motor cables may extend up to 50 m, while unshielded cables may extend up to 75 m without additional output filters. These cable allowances support flexible placement of the drive relative to the connected motor while preserving suitable electrical performance.
