Product Description:

The FC-301P1K1T2134G0680 is an AC variable frequency drive produced by Danfoss within the VLT FC 301 Automation Drives series. The unit modulates the voltage and frequency supplied to standard induction motors so plant controllers can match shaft speed to process requirements. In industrial automation, this adjustment reduces energy consumption, lowers mechanical stress, and allows accurate closed-loop torque regulation.

Rated output power is 1.1 kW, equivalent to 1.5 HP, so the drive suits small pumps, fans, or conveyors that do not exceed this rated load. It is intended for three-phase power grids operating between 200 and 240 VAC, and during continuous service, it delivers 6.6 A to the motor while drawing 5.9 A from the mains. A maximum output frequency of 590 Hz allows oversynchronous operation where high spindle speeds are required, and the internal PWM stage can switch at up to 110 kHz to maintain smooth waveforms. Overall conversion efficiency reaches 0.96, meaning only a small fraction of the supplied energy is dissipated as heat. Control wiring can range from 0.25 mm² to 1.5 mm², depending on the signal type.

Thermal planning is simplified because the worst-case power loss is only 63 W, which can be removed with forced ventilation inside a standard control cabinet. At 208 V, the apparent power drawn from the bus reaches 2.38 kVA, and it rises to 2.63 kVA when the line voltage is 230 V; these values help with sizing upstream breakers and contactors. The drive tolerates two power-ups per minute, a limit that prevents capacitor stress during frequent cycling. Motor leads may be run up to 50 m in shielded conduit or 75 m when unshielded, keeping reflected-wave voltages within acceptable limits. Digital control terminals withstand up to 28 V DC, protecting the input stage when used with common 24 V field supplies.
