Product Description:

The FC-301P3K7T2131G4529 is an AC variable-frequency drive produced by Danfoss for the VLT FC 301 Automation Drives series. As a member of this series, the unit functions as a speed regulator for induction motors, giving machine builders compact electronic control of conveyor, pump, or fan loads on production lines. By modulating output frequency and voltage, it removes the need for mechanical throttling and improves energy matching between the electrical supply and driven equipment in industrial automation.

When connected to a 208 V feeder, the drive draws an apparent power of 6.0 kVA; at 230 V, that figure rises to 6.65 kVA. These values determine the transformer capacity and protective-device ratings required upstream. Motor shaft capability reaches 5.0 HP, while the inverter can continuously deliver 16.7 A of output current to the motor terminals. During acceleration or process surges, the input side may reach 15 A, so line conductors and circuit breakers must be sized accordingly. The drive operates on three-phase power, allowing direct connection to low-voltage distribution commonly found in light-industrial plants. Its variable-frequency output supports controlled acceleration and deceleration, which can reduce mechanical stress on connected equipment during routine operation.

Electrical compatibility is centered on a mains range of 200–240 VAC, while the internal power stage provides 3.7 kW of continuous output. The control algorithms synchronize with supply grids operating at 50/60 Hz and remain stable when frequency varies by ±5 percent. Input terminals tolerate line-voltage excursions of ±10 percent without tripping, providing margin for brownouts or high-line events. The numerical identifier 301 indicates common mechanical dimensions and parameter handling across FC-301 devices, supporting consistent panel layouts and control settings within installations that use multiple drives.
