Product Description:

The FC-302PK37T5E20H1XG is an AC variable frequency drive produced by Danfoss for the VLT FC 302 Automation Drives series. It belongs to the VLT AutomationDrive FC product group and is intended to regulate the speed of induction motors in automated plant equipment such as pumps, fans, and conveyors. By converting fixed-frequency utility power into a regulated output waveform, the unit allows control systems to match motor torque to real-time load demands and reduce energy consumption across an installation.

The drive delivers a continuous shaft output of 0.37 kW, equivalent to 0.50 HP, so it fits low-power applications where precise speed regulation is required without a large thermal footprint. It accepts mains supplies from 380 – 500 VAC and uses three-phase power, allowing direct connection to standard industrial feeders without phase conversion. Once mounted, its chassis provides IP20 chassis protection, which limits the ingress of solid objects while relying on the surrounding cabinet for additional sealing. Within that enclosure, the integrated electronics apply pulse-width modulation and maintain the motor voltage-to-frequency ratio to keep flux levels consistent during acceleration, steady-state operation, and controlled deceleration.

An internal EMC network meets RFI Class A1/B (C1) emission limits, helping the complete panel meet conducted-noise requirements. Because the drive has no brake chopper, regenerated energy must be managed by a compatible external braking device if rapid stopping is required. Local interaction is handled by a graphical local control panel, which shows parameters and fault codes on its backlit display and provides direct access to commonly adjusted settings. Mechanical integration uses normal cabinet mounting for A, B, and C frames, providing a conventional installation arrangement for compatible enclosures. The cabinet must provide suitable clearance for wiring, ventilation, and access to the control panel.
