Product Description:

The FC-301PK75T2134L2963 is an AC variable-frequency drive manufactured by Danfoss for the VLT FC 301 Automation Drives series. It modulates the electrical output supplied to three-phase induction motors, allowing motor speed to follow changing process demand. This control method can conserve energy and reduce mechanical wear in pumps, conveyors, fans, and other industrial automation systems.

The inverter is rated for 0.75 kW of mechanical output, which corresponds to 1.0 HP when driving a motor at nominal load. It delivers a continuous output current of 4.6 A and operates on a 200–240 VAC three-phase power supply. Within this voltage range, the drive reaches an efficiency of 0.95, limiting heat generation as the semiconductor bridge converts incoming power into a variable-frequency waveform. The output frequency can be adjusted up to 590 Hz, while flux mode supports frequencies up to 300 Hz for high-torque operation at lower speeds. Continuous input current is 4.1 A, which should be considered when selecting conductors and upstream protective devices. Two analog inputs accept process commands such as speed references or trim values, while the analog output provides accurate feedback to supervisory control equipment.

Apparent power drawn from a 230 V source reaches 1.83 kVA, which assists with sizing upstream protection and cabling. The drive produces a power loss of 54 W, and panel airflow must remove this heat during continuous operation. The analog input converter has a resolution of 10 bit, providing 1,024 discrete levels for speed or torque commands. Its analog output uses 12-bit conversion for detailed feedback signals. The 24 V terminal supplies control logic with up to 200 mA, while a separate 10 V reference terminal supplies up to 15 mA. One Form C relay provides dry-contact signaling for status indication, fault forwarding, or connection to an external interlock.
