Product Description:

The FC-051P18KT4E20H3132F0060XCXXXSXXXX is an AC variable frequency drive manufactured by Danfoss and supplied under the VLT FC 51 Micro Drives series. Its role is to convert fixed-frequency, three-phase mains power into a modulated output so a connected control system can regulate induction motor speed and torque in conveyors, pumps, and general machinery. The compact design supports installation in small to medium automation panels where available mounting space may be limited. Adjustable motor operation can reduce energy consumption in variable-load applications and limit mechanical stress caused by abrupt starting and stopping. The drive also provides a practical method of matching motor speed to changing process demands without relying on mechanical speed-control devices.

The drive accepts a mains voltage range of 380–480 VAC, matching common industrial power supplies. It is designed for three-phase power, so no phase conversion is required when it is connected to a compatible source. Continuous output is rated at 18.5 kW, corresponding to 25 HP for the connected motor. These output values indicate the applicable motor power class and help determine the required conductors and protective devices. The control platform uses Micro Drive code 051, which identifies this model as part of the FC 51 product line. Proper cabinet ventilation is necessary to remove heat generated by the power electronics during sustained operation. Supply conditions, motor loading, and installation clearances should remain within the applicable operating limits.

The chassis has an IP20 enclosure rating, so it protects against accidental finger contact with hazardous internal parts but does not provide protection against water. Installation inside a suitable electrical cabinet is therefore required when the surrounding area contains moisture, dust, or other contaminants. The exposed heat-sink surfaces transfer operating heat to the cabinet air, making unobstructed airflow around the unit important. An integrated filter meets RFI Class A1/B requirements and helps limit conducted electromagnetic emissions on the connected supply network. Appropriate grounding and cable routing support the intended filter performance and reduce interference with nearby control and communication wiring. Separation of motor leads from low-voltage signal cables can further reduce unwanted electrical coupling. The compact chassis and integrated filtering simplify panel placement while preserving access to power, motor, and control connections.
