Product Description:

The FC-051P15KT4E20H3132F0059XCXXXSXXXX is an AC variable frequency drive manufactured by Danfoss for the VLT FC 51 Micro Drives series. The unit converts fixed-frequency line power into a modulated output, allowing control systems to vary motor speed without mechanical throttling. This capability supports efficient speed regulation for conveyors, pumps, fans, and other motor-driven equipment with changing operating demands. Its chassis-mount housing allows the compact drive to be integrated into a suitable control cabinet where installation space is limited. The drive receives external commands and adjusts its output frequency to provide controlled acceleration, deceleration, and continuous motor operation.

The drive delivers a continuous mechanical output of 20 HP, which corresponds to an electrical motor power rating of 15 kW. Its input bridge accepts a supply range of 380–480 VAC, allowing operation on common 400 V and 480 V plant power systems without transformer taps or internal reconfiguration. The rectifier is designed for a three-phase input, which distributes current across the incoming power conductors and supports stable DC-bus operation during load changes. Variable-frequency output allows the connected motor to operate at the speed required by the process instead of running continuously at full line frequency. Controlled speed changes can also reduce mechanical stress on couplings, belts, and driven equipment during starting and stopping.

The drive has an IP20 chassis rating, so it must be installed inside a switchgear or control cabinet that provides the necessary protection against dust and accidental contact. Its integrated electromagnetic compatibility network uses an RFI Class A1/B filter to reduce conducted emissions when grounding, shielding, and motor cable installation follow the applicable drive instructions. Product code 051 identifies the model within the FC 51 platform and corresponds to the terminal arrangement and parameter structure used for this drive type. Standard programming conventions provide consistent access to motor data, speed references, ramp settings, and protective functions. The compact enclosure and accessible terminals support orderly cabinet wiring while leaving adequate space for ventilation and required electrical clearances.
