Product Description:
The FC-302P45KT5131H5154H2BGXX variable frequency drive is manufactured by Danfoss for the VLT FC 302 Automation Drives series. Classified within the VLT AutomationDrive FC product group, the unit converts fixed three-phase input power into a programmable output that regulates induction motor speed in material-handling, pumping, and ventilation systems. By synthesizing voltage and frequency with insulated-gate switching, it gives controllers direct electronic control of torque and flow. Its control architecture supports consistent parameter settings across compatible FC-302 models, which simplifies integration into standardized control cabinets.
Input requirements span 380–500 VAC on a three-phase supply, allowing installation on common industrial power systems. Continuous inverter capacity reaches 45 kW, equivalent to 60 HP at the motor shaft. At rated load, the power stage operates with an efficiency ratio of 0.98, limiting heat dissipation inside the enclosure. Output frequency is adjustable up to 590 Hz; the flux-vector algorithm caps fundamental flux at 300 Hz to preserve motor magnetization. Twelve-bit analog outputs report process variables, while two relay outputs provide dry contacts for run or alarm states. The displacement factor remains above 0.98, helping keep reactive current low within the connected power system.
Dynamic braking engages at 810 V DC, a high-voltage warning occurs at 840 V DC, and an overvoltage alarm trips at 855 V DC. The rectifier tolerates a maximum mains imbalance of 3.0%, and the drive permits only one power-up per minute to prevent excessive capacitor stress. Motor connections can use up to 150 m of shielded cable or 300 m of unshielded cable without exceeding the drive’s output-filtering limits. Digital outputs can source up to 40 mA, providing adequate current for compatible control inputs and signaling devices. The true power factor remains at ≥0.9, helping reduce avoidable current demand on the plant supply. These electrical limits should be observed when selecting protective devices, routing motor conductors, and configuring the drive’s braking functions.
