Product Description:
The FC-301P30KT2131B5830 is a variable frequency drive manufactured by Danfoss for the VLT FC 301 Automation Drives series. Acting as an AC inverter, it converts fixed-frequency, three-phase mains power into a variable-voltage, variable-frequency output that allows controllers to adjust motor speed and torque in conveyors, pumps, fans, and other process equipment. The design is intended for general industrial automation applications that require high overload capacity, compact cabinet dimensions, and straightforward wiring. Its adjustable output supports controlled acceleration, deceleration, and continuous speed regulation across a range of motor-driven machinery.
The drive has a rated output power of 30 kW, which is equivalent to 40 HP and supports medium-sized production machinery. It accepts a three-phase supply of 200–240 VAC and provides a continuous motor current of 115 A under high-overload duty. At this load, the drive reaches an efficiency of 0.97, reducing the amount of heat released into the control enclosure. The control section modulates the output frequency from zero to 590 Hz, allowing operation with high-speed spindles or flux-optimized permanent-magnet motors. Built-in PI regulators and programmable ramps help maintain process stability during rapid speed changes without requiring separate control hardware for basic regulation tasks.
On the line side, the converter draws a continuous apparent power of 45.8 kVA, so upstream circuit breakers and contactors must have suitable ratings. Short-term torque surges are supported by an overload capacity of 150% for one minute during each 10-minute period, during which the power module can provide an intermittent output current of 173 A. Shielded motor cables can extend up to 50 m without additional output filters, helping the installation meet electromagnetic compatibility requirements in dense machine layouts. Power loss at full load is 1,143 W, which must be considered when sizing enclosure ventilation or other cooling provisions. The drive permits one power-up event per minute, so control sequencing must allow sufficient time between repeated starts. These operating limits help prevent excessive thermal loading of the power electronics during demanding production cycles.
