Product Description:

The FC-301PK75T2131B1094 is an AC variable-frequency drive produced by Danfoss for the VLT FC 301 Automation Drives series. It converts fixed three-phase mains power into a modulated output that lets control systems adjust the speed and torque of induction motors used in pumps, fans, and material-handling equipment. By incorporating a DC-link brake chopper and parameter-based configuration, the unit supports rapid deceleration and precise process tuning in compact control cabinets.

The drive is supplied by a three-phase line of 200–240 VAC; this voltage range covers common low-voltage plant networks while protecting components against undervoltage trips. Continuous motor current is rated at 4.60 A, establishing the thermal limit for steady-state operation. Output power reaches 0.75 kW, which corresponds to 1.0 HP. Speed regulation is possible across 0–590 Hz through the inverter’s carrier control, so standard-pole and high-pole motors can be operated across a broad speed range. The unit achieves an efficiency of 0.95 at rated current, limiting heat generation and reducing cabinet ventilation demands. The supply frequency tolerance is 50/60 Hz ±5%, and the output voltage tracks 0–100% of the input voltage. Permissible motor cable lengths are 50 m with shielded cable or 75 m with unshielded cable, providing flexibility when routing connections through machinery and control cabinets.

During short-term overloads, the inverter supplies 5.1 A, allowing acceleration of high-inertia loads without causing a drive trip. Power loss under maximum load is limited to 54 W, so thermal rise remains moderate even inside confined enclosures. The displacement power factor is >0.98, minimizing reactive current draw and supporting power quality within the facility. The brake activation voltage is 365 V DC, which establishes the threshold for operation of the integrated brake chopper. Continuous apparent power is 1.83 kVA at 230 V, indicating the electrical load handled during sustained operation.
