Product Description:

The FC-051PK75T4E20H3/PLS is an AC variable-frequency drive manufactured by Danfoss for the VLT FC 51 Micro Drives series. It converts fixed-frequency mains power into a controlled output that allows automation systems to regulate the speed of standard induction motors. By adjusting motor speed instead of relying on mechanical throttling, the unit supports efficient operation in conveyors, pumps, and ventilation systems used in industrial and commercial settings. The drive varies output frequency and voltage so connected motors can follow changing process demands with smoother starting and more controlled running speed.

The inverter accepts a supply of 380 - 480 VAC, allowing direct connection to common low-voltage distribution systems. Its continuous output is rated at 0.75 kW, which suits small machines that need accurate speed adjustment during normal operation. Because the input is three-phase, the drive distributes current across the supply conductors. The enclosure has an IP20 chassis rating, so it is intended for installation inside a control cabinet where accidental contact and dust exposure are limited. The drive also includes an RFI Class A1/B filter that helps reduce conducted emissions without adding separate external filtering hardware in many installations.

The mechanical output rating is 1.0 HP, which matches the electrical capacity of the unit. Internal code 051 identifies this version within the micro-drive platform. This output level is appropriate for fans, light conveyors, and other small-duty equipment that benefits from adjustable acceleration and deceleration. The compact product format supports panel-mounted use where available space is limited and standard induction motor control is required. It is intended for applications that need steady speed changes, straightforward integration, and reliable operation in enclosed electrical systems.
