Product Description:

The FC-051P3K0T4E20H3BXCXXXSXXX micro drive is an AC variable frequency inverter built by Danfoss for the VLT FC 51 Micro Drives series. This chassis-mounted unit converts fixed-frequency plant power into a variable output that regulates induction motor speed in conveyors, pumps, and compact processing equipment. By offering speed control in a compact footprint, it lets machine builders integrate energy-efficient motion functions without requiring large cabinet space or auxiliary cooling hardware.

The drive supplies a continuous shaft power of 3.0 kW, which is equivalent to 4.0 HP, giving it enough capacity for standard 180-frame motors on light-duty lines. Its front end accepts 380 – 480 VAC input and automatically rectifies the line to a DC bus, permitting use on common IEC voltages. Connection is made to a three-phase source, so current is shared across all supply conductors and input harmonic distortion is reduced. An enclosure rating of IP20 / Chassis indicates that live parts are finger-safe, but airflow paths remain open, so the unit should be installed inside a protective switchboard when greater ingress protection is required.

Electromagnetic compatibility is addressed by the integrated RFI Class A1/B filter, which attenuates conducted emissions for residential or light industrial limits when cable lengths are modest. To extend service life, the control board has a coated PCB finish that shields fine traces from condensation and airborne chemicals. Rapid stopping of moderate-inertia loads is handled by the built-in brake chopper, allowing external resistors to dissipate excess energy without overstressing the DC link. Field wiring enters through standard cable entries, and because no Local Control Panel, mains option, or adaptation module is fitted, setup is handled remotely through PC tools or a detachable keypad.
