Product Description:
The FC-301PK37T4134L2978 is an AC variable frequency drive manufactured by Danfoss for the VLT FC 301 Automation Drives series. Installed in control cabinets, it converts fixed-frequency three-phase mains power into a variable-frequency output for fractional-kilowatt induction motors. Electronic speed regulation allows automated conveyors, small pumps, and auxiliary HVAC fans to match process demand without mechanical throttling. The unit follows the VLT AutomationDrive FC architecture, keeping its I/O terminals and mechanical footprint consistent with related models in the FC 301 family. The shared terminal arrangement supports consistent control wiring and parameter use across these related drive models.
The rated motor output is 0.37 kW, which is equivalent to 0.50 HP. The input bridge accepts 380–480 VAC three-phase power, and the drive can supply up to 1.3 A to the motor windings when operating from a 380–440 V source. Apparent power demand reaches 0.9 kVA, which can be used to size feeders and circuit breakers. An electrical conversion efficiency of 0.93 limits wasted energy and helps reduce the cooling demand inside the control cabinet. These electrical characteristics suit small constant-torque loads connected to common industrial power systems.
Total power loss is 35 W, allowing the integrated heat sink to dissipate energy without an external fan. The high-speed pulse input handles frequencies up to 110 kHz for encoder feedback or flow metering. Digital command lines tolerate up to 28 V DC with an impedance of 4 kΩ, allowing PLC outputs to drive the inputs directly. One transistor output supplies 40 mA for run-status signaling, while an integral relay switches 2 A at 240 V AC for motor contactor control. Motor cables can extend up to 50 m in shielded runs or 75 m in unshielded runs, providing flexibility in drive-to-motor placement within industrial equipment.
