Product Description:

The FC-302P11KT5E20H1B is an AC variable frequency drive produced by Danfoss within the VLT FC 302 Automation Drives series. The unit receives a fixed electrical supply and generates a variable-frequency, variable-voltage output that allows control systems to adjust induction motor speed on demand. In automated conveyors, centrifugal pumps, and ventilation fans, this electronic modulation maintains torque accuracy, reduces energy use, and supports processes that require frequent acceleration, deceleration, or steady low-speed operation.

The drive supplies continuous motor power of 11 kW, equivalent to 15 HP, making it suitable for midrange motion tasks in packaging and material-handling systems. Its rectifier and inverter stages accept an incoming line voltage of 380–500 VAC through a three-phase power supply commonly used in plants operating at 50 or 60 Hz. Protection is provided by an IP20 chassis enclosure, so the heat sink and terminals must be installed inside a ventilated panel that prevents exposure to dust, liquids, and accidental contact. This enclosure arrangement requires adequate panel airflow, suitable conductor sizing, and sufficient clearance around heat-producing components.

Dynamic stopping energy is managed by an internal brake chopper, which diverts regenerative voltage into a connected braking resistor circuit supervised by the control board. Conducted emission compliance is supported by a built-in filter rated for RFI Class A1/B (C1), which minimizes high-frequency noise on the supply conductors when the cabinet uses the recommended grounding practices. Mechanical placement uses a normal cabinet mount for A, B, and C frames, allowing a consistent back-panel arrangement across the supported frame sizes. The mounting pattern also provides stable support for the chassis while preserving access to power terminals, control wiring, and ventilation paths within the panel.
