Product Description:
The FC-301P11KT4134L2987 is an AC variable-frequency drive produced by Danfoss within the VLT FC 301 Automation Drives series. It converts fixed three-phase mains power into a modulated output that lets controllers vary induction-motor speed and torque for conveyors, pumps, and general process equipment. By handling acceleration, deceleration, and steady-state operation electronically, the drive replaces mechanical throttling devices and lowers energy use in industrial automation systems.
The power section accepts 380–480 VAC and is rated for continuous delivery of 11 kW, equivalent to 15 HP at the motor terminals. Compatibility with three-phase power simplifies connection to standard plant distribution networks. The thermal design permits full-load operation at temperatures up to 45 °C without derating, so cabinet cooling demands remain moderate. Two low-level supplies are available for sensors and reference potentiometers: a 10 V output can source 15 mA, and a 24 V output supports 200 mA. Both low-level supplies are isolated from the mains path. Logic inputs tolerate up to 28 V DC and present an impedance of 4 kΩ, allowing direct wiring to PLC discrete outputs without additional buffers. An AC-1 relay contact rated for 240 V AC and 2 A is provided for run-status signaling or external brake-release commands.
Motor conductors may have a cross-sectional area of up to 10 mm² (7 AWG), and shielded motor cable runs are limited to 50 m to minimize radiated noise. Unshielded motor cable runs can extend to 75 m. The DC bus triggers an overvoltage alarm at 820 V DC, while the internal brake chopper activates at 778 V DC to divert excess regenerative energy. The drive has an IE2 efficiency classification. The STO safety input draws 50 mA RMS at 24 V, enabling integration into emergency-stop chains without dedicated relays.
