Product Description:

The FC-051P7K5T4E20H3BXCXXXSXXX is an AC variable frequency drive produced by Danfoss for the VLT FC 51 Micro Drives series. As a compact inverter, it regulates induction-motor speed in small conveyors, pumps, and fan applications, giving basic automation lines adjustable torque without mechanical throttling. By varying motor voltage and frequency together, it lets connected equipment run at speeds matched to process demand instead of fixed line frequency. Its compact format suits installations where panel space is limited and simple variable-speed control is required. The unit serves as the interface between a fixed-frequency plant supply and the motor by generating controlled output frequency and voltage.

The drive delivers a continuous power of 7.5 kW, corresponding to 10 HP at the motor shaft. It accepts mains inputs from 380 - 480 VAC on a three-phase network, so it ties directly into common industrial panels without step-down transformers. Internally, an insulated-gate bipolar transistor bridge chops the DC bus at high carrier frequency, and a dedicated brake chopper channel dissipates regenerated energy during rapid deceleration to protect the DC link. The design omits a mains option module and ships without a local control panel. Parameters are set through external fieldbus or PC tools.

The electronics have an IP20 / Chassis protection rating, allowing installation inside a ventilated cabinet where only solid objects larger than 12 mm can enter. Emission control is assisted by an integrated RFI Class A1/B filter, which reduces conducted noise on the supply leads for general-purpose EMC environments. The printed circuit boards have a coated PCB finish that helps guard against humidity and airborne contaminants in light industrial environments. Power and control wiring pass through standard cable entries, so no specialized glands are needed. This layout supports straightforward cable routing in compact control enclosures.
