Product Description:

The FC-301PK75T4134L2641 is a variable-frequency drive manufactured by Danfoss for the VLT FC 301 Automation Drives series. It accepts an industrial three-phase mains supply and produces a regulated output for controlling motor speed. This capability supports conveyors, pumps, and fans by improving process flexibility and reducing energy consumption in automated equipment. The drive can respond to control-system commands by adjusting output frequency and voltage according to changing operating demands.

This model is rated for 0.75 kW (1.0 HP) and connects to supplies ranging from 380–480 VAC. At 400 V, it delivers a continuous output current of 2.4 A with an apparent power requirement of 1.7 kVA. Its efficiency reaches 0.96 at rated current, and the IE2 energy-efficiency class indicates compliance with current drive standards. The unit supplies an auxiliary voltage of 10.5 V ±0.5 V for analog references and another auxiliary voltage of 24 V (+1/−3 V) for digital sensors or brakes. These rails can source up to 15 mA and 200 mA, respectively, helping protect low-power field devices from overload. The converter can operate at ambient temperatures up to 45 °C under full load. It also tolerates a maximum incoming phase imbalance of 3.0% without derating.

Power losses are limited to 46 W at rated load, helping control heat accumulation inside electrical cabinets. The displacement power factor is >0.98, reducing reactive demand on the supply network, while the true power factor is at least 0.9 under rated operating conditions. The drive draws an input current of 2.2 A under the stated voltage and load conditions. Its relay output can switch 240 V AC at 2 A for motor contactor control or alarm signaling. The available analog and digital connections allow the drive to exchange reference, status, and control signals with compatible automation equipment without unnecessarily complicating the external wiring layout.
