Product Description:
The FC-051PK75S2E is a compact AC variable-frequency drive from Danfoss within the VLT FC 51 Micro Drives series. Classified under the VLT Micro Drive product group, this controller regulates the speed of small induction motors used in conveyors, fans, and dosing pumps throughout automated installations. Its compact housing measures 70 mm wide, 150 mm high, and 148 mm deep, allowing installation in panels with limited space. The M1 frame weighs only 1.1 kg, which minimizes the load placed on the mounting surface. Two analog inputs, five digital inputs, one analog output, and one relay output provide direct connections for machine controls and process signals.
The drive accepts a mains input of 200 to 240 VAC and is designed for single-phase power commonly available in light-industrial panels. Within this input range, the inverter can deliver 0.75 kW of mechanical shaft power to the connected motor. During continuous operation, the output stage supplies 4.2 A to support steady motor loading without exceeding its normal current capacity. Transient operating conditions can draw up to 11.6 A from the supply, so conductors and upstream protection must accommodate brief increases in input demand. A properly selected line fuse protects the wiring and power electronics against excessive current caused by faults.
For intermittent acceleration or momentary process jams, the drive tolerates an overload of 150% for 1 minute, enabling a short increase in motor torque before protective limiting occurs. The recommended upstream protection is a 25 A gG fuse, which clears severe short-circuit currents while accommodating the initial charging current of the DC-link capacitors. The IP20 enclosure protects against contact with hazardous internal parts but does not provide protection from water. Installation inside a suitable cabinet is therefore necessary where moisture, conductive debris, or accidental access may occur. The narrow housing leaves space for neighboring control equipment, while the available analog, digital, and relay connections allow the drive to interface directly with common automation devices.
