Product Description:

The FC-301PK75T2134L2896 is a variable frequency drive manufactured by Danfoss for the VLT FC 301 Automation Drives series. It modulates three-phase power to regulate the speed of standard induction motors in automated equipment such as conveyors, centrifugal pumps, and small HVAC fans. By integrating control, protection, and fieldbus options in a single enclosure, the drive supports compact machine designs while maintaining compatibility with the wider VLT AutomationDrive FC product group.

The inverter has a continuous motor rating of 0.75 kW, which corresponds to 1.0 HP, making it suitable for low-power applications that require closed-loop speed control. It accepts a three-phase supply of 200 to 240 VAC and delivers a continuous output current of 4.6 A while drawing 4.1 A from the supply at rated load. These electrical limits determine the appropriate cable size, fuse selection, and upstream circuit breaker coordination for a cabinet installation. Apparent power reaches 1.83 kVA, and the design tolerates a mains imbalance of 3%, helping prevent nuisance trips when phase voltages are slightly uneven. The built-in relay can switch 2 A at 240 V AC, enabling direct control of contactors or warning lamps without auxiliary relays.

Conversion efficiency is 0.95 at rated current, with a thermal loss of 54 W that must be removed through adequate panel ventilation. The input section operates across a supply frequency range of 50/60 Hz ±5%, allowing use with common industrial power systems. Control feedback is supported by a 12-bit analog output that provides process variables with precise resolution. Four digital inputs with 4 kΩ impedance accept signals from push buttons or PLC outputs. A digital transistor output supplies up to 40 mA for status indicators, while shielded motor cables can extend up to 50 m without exceeding EMC limits or overloading the drive’s dV/dt filters.
