Product Description:
The FC-301PK75T4134L2912 is a variable frequency drive from Danfoss in the VLT FC 301 Automation Drives series. The unit controls the speed of three-phase motors in industrial automation, allowing precise adjustment of flow, pressure, and motion profiles without mechanical throttling. Installed between the mains supply and the motor, the controller provides closed-loop regulation that can reduce energy consumption and limit inrush current during acceleration. Its control functions support applications such as pumps, conveyors, fans, and other machinery that requires adjustable motor speed.
This model delivers a continuous mechanical output of 0.75 kW and accepts a mains voltage range of 380–480 VAC. Input current is 2.2 A at 380–440 V and 1.9 A at 441–500 V. The inverter provides a maximum motor frequency of 590 Hz, while flux-mode operation has a 300 Hz ceiling for field weakening. Output current reaches 2.4 A on 380–440 V systems and 2.1 A at higher voltages, resulting in an apparent power demand of 1.7 kVA. Drive efficiency at rated current is 0.96, and the displacement power factor is >0.98. An internal DC-link choke supports a true power factor of at least 0.9 and helps reduce line-current distortion. Two digital transistor outputs are available, and each output can source up to 40 mA for status relays or counter inputs. The power section is configured for three-phase power.
The controller supports motor cables up to 50 m when shielded and up to 75 m when unshielded, providing flexibility when the motor is installed away from the control cabinet. Shielded cable can help reduce electromagnetic interference in installations containing sensitive control or communication equipment. The longer unshielded allowance can accommodate layouts where shielding is not required by the surrounding electrical environment. Thermal losses are limited to 46 W at full load, which reduces heat accumulation inside the enclosure and simplifies ventilation planning. The FC 301 platform provides adjustable motor control for processes that require regulated acceleration, deceleration, torque, and speed. Its digital outputs can also communicate operating states to external control circuits without requiring separate signal converters.
