Product Description:

The FC-051P3K0T4E20H3BXC is an AC variable frequency drive manufactured by Danfoss for the VLT FC 51 Micro Drives series. As a compact member of the VLT Micro Drive product group, the unit modulates incoming line power to regulate induction motor speed in conveyor sections, pumps, and general machine modules. Its design fits decentralized panels where simple speed control is required, providing a small-footprint drive that handles routine acceleration, deceleration, and current limiting tasks inside automated equipment.

The drive delivers 3.0 kW of continuous output, which is equivalent to 4.0 HP, so it can operate medium-frame IEC motors without derating. It accepts a supply range of 380 – 480 VAC on a three-phase circuit, allowing direct connection to common industrial feeders. With its enclosure classified as IP20 / Chassis, the device is intended for mounting inside a ventilated panel where operators are protected against accidental contact while the unit remains open to cabinet airflow. The micro drive series identifier 051 keeps the mechanical height below that of larger VLT controllers, which helps simplify retrofit work in crowded installations.

An integrated RFI Class A1/B filter attenuates conducted noise so the inverter can share power rails with sensitive sensors. Braking energy is routed through the internal brake chopper, removing the need for an external resistor switch during rapid-stop duty cycles. All circuit boards carry a coated PCB finish that shields fine-pitch components from moisture, dust, and flux residue in standard factory atmospheres. The drive is supplied with no local control panel, so setup is performed by a remote LCP or through parameter upload by way of the serial service port.
