Product Description:

The FC-302PK55T5E20H1BN is an AC variable frequency drive manufactured by Danfoss for the VLT FC 302 Automation Drives series. It converts fixed-frequency mains power into a variable output so plant controllers can adjust induction-motor speed and torque, improving energy use and process accuracy on conveyors, pumps, fans, and other three-phase loads.

Within the drive, a continuous output of 0.55 kW sets the electrical power available to the motor terminals under rated thermal conditions. The input section accepts mains in the range of 380 – 500 VAC, allowing direct connection to common industrial feeders without step-up transformers. Operation is based on Three Phase Power, so balanced line currents are maintained during acceleration and braking. Electromagnetic compatibility is aided by the integrated RFI Class A1/B (C1) filter, which limits conducted emissions back onto the supply. For electrical safety, the chassis carries a IP20 / Chassis protection rating, meaning live parts are finger-safe when the unit is cabinet-mounted. These characteristics place the inverter in the VLT AutomationDrive FC product group under the internal 302 identifier.

To supplement the electrical envelope, the drive provides 0.75 HP of mechanical output when ratings are stated in imperial units. Controlled stopping of the connected motor during power loss or emergency events is handled by a brake chopper, which directs excess regenerative energy to an external resistor. Onboard interaction takes place through the Numerical Local Control Panel, giving parameter access without external tools. Mechanical integration is straightforward because the heatsink is designed for Normal cabinet mount A, B & C Frames, enabling placement alongside other automation devices inside standard enclosures. Together, these functions extend the capabilities established by the core power ratings and make the inverter suitable for compact process machines.
