Product Description:
The Danfoss FC-051P18KT4E20H3BXCXXXSX is an AC variable-frequency micro drive in the VLT FC 51 Micro Drives series. Intended for cabinet installation, the unit modulates the mains supply so induction motors can accelerate, decelerate, or run at a fixed speed without mechanical throttling. By converting fixed-frequency line power into a pulse-width-modulated output, the drive serves pumps, fans, and conveyors in automated production cells. This arrangement gives the connected motor adjustable speed control with smoother process regulation than fixed-speed operation.
The power section is rated at 18.5 kW, which corresponds to a mechanical output of 25 HP. It accepts a supply of 380-480 VAC on a three-phase network, so it connects directly to common industrial mains. An internal DC link and insulated-gate bipolar transistors generate the output waveform, while an IP20 chassis enclosure is intended for use in a ventilated control panel. Because no dedicated mains option is installed, external line reactors or filters may be required where additional harmonic mitigation is needed.
Electromagnetic compatibility is supported by an integrated RFI Class A1/B filter that attenuates conducted noise on symmetrical and asymmetrical paths. Dynamic overvoltage energy is handled by a built-in brake chopper, allowing connection of a braking resistor for rapid deceleration cycles. Circuit reliability in humid or dusty atmospheres is improved by a coated PCB finish, and field wiring is simplified through standard cable entries on the baseplate. The drive is supplied without a local control panel, so parameter access is handled through remote terminals, and the no-adaptation selection keeps the unit in its baseline form. This helps the drive fit compact machine panels where direct front access is not required during normal operation.
