Product Description:

The FC-051PK37S2E20H3XX micro drive is produced by Danfoss as part of the VLT FC 51 Micro Drives series. Designed for cabinet installation, the unit functions as a variable-frequency converter that supplies adjustable AC voltage and frequency to fractional-horsepower induction motors. Within automated conveyors, compact pumps, and small fan modules, the drive provides speed and torque regulation in response to analog or digital commands. This capability allows machine builders to improve energy efficiency and process control without adding bulky mechanical speed-control devices.

The drive’s continuous output is rated at 0.37 kW, indicating the electrical power it can deliver to the motor terminals under steady thermal conditions. This output corresponds to 0.50 HP, making the device suitable for light-duty axes and auxiliary equipment. It accepts a mains supply ranging from 200–240 VAC, so it can connect directly to standard low-voltage power sources found in workshops and original equipment manufacturer panels. The drive uses a single-phase input, and its front-end rectifier accommodates a two-wire line connection with protective grounding rather than a three-phase line configuration. An enclosure rating of IP20 provides protection against accidental finger contact with internal components, but the chassis must be installed inside a closed electrical cabinet.

In noise-sensitive installations, the integrated filter meets RFI Class A1/B, reducing conducted emissions on the supply network without requiring an external filter. The model has no brake chopper, so applications that generate substantial energy during rapid deceleration require external braking equipment or a mechanical brake. The drive also has no local control panel, which keeps the form factor compact and requires parameter entry through compatible remote controls or communication commands. Internal code 051 identifies the unit as a member of the VLT FC 51 Micro Drive product line. These operating and interface features support installation in compact control cabinets where space is limited and motor speed must be adjusted electronically.
