Product Description:

The FC-301P1K5T4E20H1 is an AC variable frequency drive manufactured by Danfoss as part of the VLT FC 301 Automation Drives series. The unit converts fixed-frequency mains power into a controlled output waveform, allowing a plant controller to regulate induction motor speed and torque according to changing load conditions. It is suitable for pumps, fans, conveyors, and other automated machinery that requires adjustable motor operation. Controlled acceleration and deceleration can reduce mechanical stress associated with direct starting, abrupt stopping, and repeated on-off cycling.

The mains input range is 380–480 VAC, and the power section accepts three-phase power from common industrial distribution networks. The inverter provides a continuous motor output of 1.5 kW, corresponding to 2.0 hp. This output capacity supports smaller industrial motors used in material handling, ventilation, fluid circulation, and similar applications. Control electronics and electrical terminations are protected by an IP20 chassis enclosure, which guards against accidental contact with internal components but does not provide protection from water. The drive must therefore be installed inside a suitable control cabinet that provides the required protection from moisture, dust, and other contaminants. Accessible control terminals and a structured parameter interface support connection to external sensors, motor controls, and plant automation equipment.

An integrated RFI Class A1/B filter attenuates conducted electromagnetic emissions at the drive terminals, helping limit interference with nearby control equipment. The housing supports normal cabinet mounting for A, B, and C frames, allowing the drive to be arranged alongside compatible panel components without custom mounting brackets. Its mounting arrangement also supports orderly routing of mains, motor, and control wiring within the cabinet. The internal 301 designation identifies the drive platform and its associated parameter structure, communication options, and control functions. Variable-frequency output allows motor speed to follow process demand instead of remaining fixed at the mains frequency. This operating method can reduce unnecessary energy use in variable-torque applications while providing smoother motion than throttling devices or frequent direct switching. Proper cabinet spacing and ventilation are still required to remove heat from the power electronics during continuous operation.
