Product Description:

The FC-301PK25T2134L2929 variable frequency drive is produced by Danfoss for the VLT FC 301 Automation Drives series. Within an industrial panel, the unit synthesizes a controllable AC waveform, allowing PLCs to command motor speed and torque electronically instead of relying on dampers or gear changes. Its power range and control interfaces make it suitable for fractional-horsepower pumps, compact material-handling belts, and other low-inertia machine axes.

The inverter delivers up to 0.25 kW of electrical output, corresponding to 0.33 HP, and it is designed for a three-phase supply of 200–240 VAC. At nominal load, the drive supplies a rated current of 1.8 A, while its output frequency can be set anywhere from zero to 590 Hz for a wide speed-control range. Internally, the controller samples process commands with a 10-bit analog input and reports data through a 12-bit analog output. A maximum input current of 1.6 A keeps the required wiring size small, and the magnetic flux frequency is limited to 300 Hz to protect the motor core. The drive uses three-phase input power and provides variable-frequency output for compatible AC motors.

In continuous service, the drive reaches an efficiency of 0.94 and produces only 21 W of heat at rated load, easing cabinet ventilation requirements. The displacement factor remains greater than 0.98, and the true power factor is at least 0.9, so upstream breakers experience little reactive current. For short demand peaks, it supports an overload capacity of 160% for one minute in every ten-minute period, with a limit current of 2.0 A. The control scheme permits a maximum of two power-ups per minute, preventing excessive stress from repeated startup cycles. The drive maintains its performance with a shielded motor cable up to 50 m long. Its apparent power is 0.65 kVA at 208 V, which supports operation in compact motor-control applications.
