Product Description:

The FC-051PK37S2E20HXXXCXXXSXXX is an AC variable-frequency micro drive manufactured by Danfoss within the VLT FC 51 Micro Drives series. Designed for compact panel installations, it regulates the speed of small induction motors in conveyors, pumps, or fan applications across general automation tasks. By converting single-phase mains to an adjustable three-phase output, the device supplies precise torque control while conserving energy in light-duty machinery.

Electrically, the unit delivers a continuous output of 0.37 kW, matching motors up to its fractional-kilowatt rating. It accepts an input of 200 – 240 VAC on a Single phase feeder, so it can be powered from standard low-voltage distribution without a transformer. Internal power components are protected by an IP20 / Chassis housing that allows mounting inside ventilated enclosures while preventing accidental contact. The control and power boards carry a Coated PCB finish that resists airborne moisture and dust, extending service life in industrial environments. Danfoss lists the internal build code as Micro Drive series 051, confirming dimensional and software compatibility with the broader VLT Micro Drive product group.

Mechanical integration is simple because Adaptation A specifies Standard Cable Entries, eliminating special gland plates, while Adaptation B is listed as no adaptation, so the frame ships without custom hardware. When connected to a motor rated at 0.50 HP, the drive can supply the full torque envelope without derating. Safety stopping energy is managed externally because the design includes No brake chopper, so dynamic braking resistors are not supported. The front panel designation “No Loc. Cont. Panel” means local keypad control is omitted, and “No Mains Option” indicates that no additional EMC filter or disconnect module is factory-fitted. Firmware arrives as Latest release std. SW., ensuring parameter menus match current Danfoss support tools.
