Product Description:
The FC-301P15KT4E21H1 variable frequency drive is produced by Danfoss and belongs to the VLT FC 301 Automation Drives series. Designed for cabinet integration, the unit converts fixed-frequency mains power into a regulated output that allows control systems to vary the speed of induction motors on conveyors, mixers, and pump skids. This adjustable output supports controlled acceleration and process-speed regulation while helping equipment match motor operation to changes in production demand.
The drive delivers a continuous output of 15 kW, making it suitable for midrange pumping, fan, and material-handling applications that require stable torque at varying speeds. It accepts line supplies from 380–480 VAC, allowing direct connection to common industrial low-voltage networks without an additional transformer. The input uses three-phase power, which distributes the electrical load across the supply phases and supports operation with standard industrial motors. An integrated RFI Class A1/B filter attenuates conducted emissions, reducing the effect of switching noise on nearby instrumentation and control wiring. The IP21 / Type 1 enclosure rating provides protection against accidental contact and vertically falling water drops when the drive is installed in an appropriate indoor location. Adequate cabinet ventilation and clearance should be maintained so heat produced by the power electronics can escape during continuous operation.
The drive supports dry-room mounting with B, C, D, and E frames, allowing the installation layout to accommodate the applicable cabinet depth, airflow path, and heat-dissipation requirements. Its internal code 301 identifies the FC 301 product line and its associated automation-control capabilities. Closed-loop vector control enables the inverter to regulate motor torque and speed more precisely when suitable feedback and control components are used. Energy-saving functions allow motor output to follow actual process demand instead of requiring continuous full-speed operation. The available parameter menus and fieldbus options also support integration with automated material-handling equipment and other coordinated control systems.
